How did that get away?

BGM kept looping after exiting credits_a3, which is not what we want.
Lowered the volume of Credits A3 by a factor of 10.

+
+Git / Repo conventions
+----------------------
+
+In general, use `kebab-case` for branch names. Also, make sure they're concise and descriptive - like 2 or 3 words is usually good.
+
+```
+* badbeef (badBranchName) This branch name is bad.
+| * defaced (another_bad_branch_name) This branch name is also bad because it uses snake case.
+|/
+| * deadcab (generic) This branch name isn't very descriptive.
+|/
+| * bac0040 (this-long-winded-branch-name-that-could-be-its-own-commit-message) Self-explanatory.
+|/
+| * 600db01 (good-branch-name) This branch name is good.
+|/
+* 0000420 (HEAD -> master, tag: v0.6.9) This is a sexy root commit.
+```
+
+The top line of a commit message should generally be one full sentence long, without too many subordinate clauses. Don't sweat 50/72, but try not go over about 100 characters either.
+* If the message starts with a verb, it should be written in the past tense, as a description of what the commit _did_ to the commit tree. (e.g. _Made_ a change, _Fixed_ a bug, _Added_ a feature)
+* Alternatively, include a description (in the present tense) of what is now true thanks to this commit. (e.g. "The Puyo Puyo mode can now support up to 50 players.")
+
+```
+* 800000d (message-too-long) Made multiplayer stuff play well with the new v0.2.5 server by fixing a problem the client was having with sending multiple 4-KB packets within 2 milliseconds of each other.
+| * defaced (not-descriptive-enough) Fixed stuff.
+|/
+| * bad0003 (present-tense) Lengthens the retry period of the server connection to 15 seconds.
+|/
+| * bad0004 (imperative-mood) Force the credit roll to end after 67 seconds if no input is detected.

+| * 600d002 (also-good) Backgrounds don't suck anymore.
+|/
+* 1234567 (HEAD -> master, tag: v0.4.2) Updated docs in preparation for a new release.
+```
+
+When making pull requests, always include:
+
+* A title that works well as a commit title, since that's what's going to appear when it's merged.
+* A full description of the problem that the pull request solves or the feature that it implements.
+	* If the whole purpose of the pull request is to resolve a particular issue and nothing else, "Fixes #[issue number]" counts as a full description. Otherwise if there's anything else in the pull request, make a short note of "also [did this other thing]".
+
+
+Coding conventions
+------------------
+
+Use tabs to indent, spaces to align.
+
+* Specifically, spaces should not appear at the beginning of a line, and tabs should not appear _except_ at the beginning of a line.
+* The sole exception is in a multiline `if` statement; the initial `if` should have four spaces before it to align it with an `elseif` on the next line. For example:

+	elseif self.level < 1200 then return 8
+	else return 6 end

+
+Comments at the end of lines of code must be one line long. Multi-line comments must appear in their own block.
+
+```lua
+	if not self.piece:isDropBlocked(self.grid) then
+		-- this is a comment that appears in a block of its own, separate from any code

-Marathon 2020
-=============
-
-To celebrate the coming of the year 2020, I've created a new "extended Tetris the Grand Master" mode where the level counter goes up twice as far as normal, all the way up to 2020.
-
-
-Gameplay
--------
-
-The goal of this game is to reach the end at level 2020.
-
-Every piece placed increases the level by 1, and every line cleared also increases the level by 1, with bonuses for large numbers of lines:
-
-| Lines cleared | Levels advanced |
-|---------------|-----------------|
-| 1 | 1 |
-| 2 | 2 |
-| 3 | 4 |
-| 4 | 6 |
-
-When the current level reaches one less than the level at the bottom of the display (usually a multiple of 100), the level will not advance until a line is cleared.
-
-
-Levels
------
-
-Each section is 100 levels long, except for the last section, whose levels go from 1900 all the way to 2020.
-
-However, it is possible to be stopped early on if you do not play fast enough.
-
-
-### Torikans
-
-There are certain checkpoints at which your current time will be checked and you will be stopped if your time is over a set objective time.
-
-| Level | Time limit |
-|-------|------------|
-|   500 |   6:00.00  |
-|   900 |   8:30.00  |
-|  1000 |   8:45.00  |
-|  1500 |  11:30.00  |
-|  1900 |  13:15.00  |
-
-At levels 500, 1000, and 1500, you will be stopped immediately if your time is not under the objective.
-
-At levels 900 and 1900, the next section will be capped at 999 or 1999 respectively, and you will get a short credit roll when the section is over.
-
-
-Speed
-----
-
-Marathon 2020 gets faster in two different, independent ways, the gravity curve and the delay curve.
-
-The gravity curve is always the same at a particular level, while the delay curve can vary based on your previous section time.
-
-### Gravity Curve
-
-The gravity curve is the same as it is in the original TGM and TAP.
-
-### Delay Curve
-
-The delay curve is shown as in the following table. Line ARE is always equal to ARE.
-
-If your time in a particular section from 0 to 70 is smaller than the "cool" requirement at that level, your delay curve will be bumped up an extra level at the end of the section.
-
-The delay curve always advances at least 1 level past level 500, and if you get a section cool when the level is past 500, it will advance 2 levels instead.
-
-| Level | ARE  | Lock | DAS  | Line | Cool |
-|-------|------|------|------|------|------|
-|0|27|30|15|40|45.00|

-
-In order to get a section cool, your 0-70 section time must be below the cutoff *and* no more than 2 seconds slower than your previous 0-70 time.
-
-
-Grading
-------
-
-
-
-
-### Basic grades
-
-Internally, the grade counter is a number that can range from 0 to 30.
-
-At the beginning of the game, it starts at 0. To increase it, you must bring an internal grade point counter past a certain threshold.
-
-The threshold is set at 50 points for the first grade, then 100 more points for the next grade, then 150 points for the grade after that, and so on. You reach the maximum level of 30 at a total of 23,250 points.
-
-A table of the thresholds in grade points required to reach each level is provided below:
-
-Grade|Threshold
-|-
-0|0
-1|50
-2|150
-3|300
-4|500

-28|20300
-29|21750
-**30**|**23250**
-
-Points are given according to a different scale, the point level. The point level is calculated by taking your current actual level, and adding (100 * the delay level) to it.
-
-The points given for clearing certain amounts of lines is given as follows:
-

-
-Past level 1000, a 4-line clear will always give (30 * current grade), regardless of point level.
-
-The remaining 20 grades come from section cools. Every section cool you get boosts your score by one grade. There are no regrets.
-
-Points are also taken away with the time it takes to lock down a piece. The delay counter starts at 0, and increases by (current grade + 2) every frame. When the counter reaches or exceeds 240, it resets to 0, and 1 grade point is taken away.
-
-Grades are based on the maximum grade points achieved. Once a grade has been attained, it cannot be lost even if grade points drop below the threshold for that grade.
-

-Phantom Mania 2
-===============
-

-Gameplay
--------
-
-The goal of this game is to reach the end at level 1300, and then score as many grades as possible in the ending credit roll.
-
-Each piece disappears as soon as it is placed down. Only the active piece is visible at any given time.

-Every piece placed increases the level by 1, and every line cleared also increases the level by 1, with bonuses for large numbers of lines:
-
-| Lines cleared | Levels advanced |
-|---------------|-----------------|
-| 1 | 1 |
-| 2 | 2 |
-| 3 | 4 |
-| 4 | 6 |
-
-When the current level reaches one less than the level at the bottom of the display (usually a multiple of 100), the level will not advance until a line is cleared.
-
-
-Levels
------
-
-Each section is 100 levels long. At certain levels, the speed may get faster, or the difficulty may increase some other way.
-
-| Level | What happens |
-|-------|------------|
-|   500 | Rows of garbage start to advance on the board. The bottom row is copied, appearing for a brief flash before disappearing again. |
-|  1000 | The garbage stops, but the hold queue turns invisible. |
-|  1100 | The first next preview turns invisible. |
-|  1200 | The second next preview turns invisible. |
-
-Unlike in Shirase mode, the speed of the game does not get faster past level 1000.
-
-### Torikans
-
-There are certain checkpoints at which your current time will be checked and you will be stopped if your time is over a set objective time.
-
-| Level | Time limit |
-|-------|------------|
-|   300 |   2:02.00  |
-|   500 |   3:03.00  |
-|   800 |   4:45.00  |
-|  1000 |   5:38.00  |
-
-At each torikan, you will get a 54-second invisible roll which is worth grade points.
-
-Only the 1300 roll is in Big Mode.
-
-
-Grading
-------
-
-Your grade starts at 1, and goes on from S1 to S9, and then M1 upwards indefinitely.
-
-Your grade advances each section based on your section time. If you achieve a section COOL, you get 2 grade points. If you instead incur a section REGRET, you get no grade points. The normal section time (in between COOL and REGRET) is worth one grade point.
-
-| Level | Section COOL | Section REGRET |
-|-------|--------------|----------------|
-|  0-4  |     36.00    |      48.00     |
-|  5-9  |     30.00    |      39.00     |
-| 10-12 |     27.00    |      35.00     |
-
-
-Then, the invisible roll is also worth grade points.
-
-| Lines cleared | Grade points |
-|---------------|--------------|
-|       1       |     0.02     |
-|       2       |     0.06     |
-|       3       |     0.15     |
-|       4       |     0.40     |
-|     Clear     |     1.00     |
-
-
-The number of grade points you earn correspond to your grade as follows:
-
-| Points |  Grade |
-|--------|--------|
-|    0   |    1   |
-|    1   |   S1   |
-|    2   |   S2   |
-|    3   |   S3   |
-|    4   |   S4   |
-|    5   |   S5   |
-|    6   |   S6   |
-|    7   |   S7   |
-|    8   |   S8   |
-|    9   |   S9   |
-|   10   |   m1   |
-|   11   |   m2   |
-|   12   |   m3   |
-|   13   |   m4   |
-|   14   |   m5   |
-
-And so on. For *x* > 9 grade points, your grade is m(*x*-9).
-
-If you achieve a section COOL on each section, your rank will be m17 entering the credit roll.

@@ -10,16 +10,13 @@ A ruleset consists of the following things:

 If you're used to Nullpomino, you may notice a few things missing from that definition. For example, piece previews, hold queues, and randomizers have been moved to being game-specific rules, rather than rules that are changeable with the ruleset you use. Soft and hard drop behaviour is also game-specific now, so that times can be more plausibly compared across rulesets.

+There are six rulesets currently supported:

-Rotation system
---------------
-A rotation system defines the following things:
- * The block offsets of each piece orientation.
- * The wall or floor kicks that will be attempted for each type of rotation.
+* Cambridge - a ruleset original to Cambridge, used for all custom modes. Supports 180-degree rotations!

-There are four rotation systems currently supported:
+* SRS - the rotation system used in the Tetris Guideline games. Supports 180-degree rotations!
+* Ti-SRS - SRS but with no 180-degree rotations.

-* Cambridge
-* Classic ARS
-* Ti-ARS
-* SRS
+* ARS - the rotation system from the original Tetris the Grand Master.
+* Ti-ARS - ARS with floorkicks! From TGM3: Terror Instinct.
+* Ace-ARS - ARS with floorkicks and move reset! From TGM ACE.

Joe Z	901f7f2d12	Fixed a bug in the "actual cleared row count" for Big Mode.	2019-06-22 00:07:10 -04:00
Joe Z	35f4aea67d	Added Ti-SRS and modified delay curve behaviour on Marathon 2020. I realized that playing at 4/8 for 800 levels straight is probably too much, so I made it that only the first 10 sections count for advancing the delay curve faster than it would normally go. Now only the last 500 levels can be at delay level 20.	2019-06-21 23:44:58 -04:00

Joe Zeng	5c5ffc6887	Added Big Mode as a piece type. (#20 ) Survival A3 and Phantom Mania 2 are now in their fully complete glory! :D Implements #13.	2019-06-16 22:16:09 -04:00
Joe Zeng	5131061e42	Added conventions for code submission / review. Also, coding conventions didn't deserve to go first, so I reordered the sections a little bit.	2019-06-15 23:28:53 -04:00
Joe Z	209e60e82e	Fixed a roll and section COOL bug in Marathon A3.	2019-06-09 18:37:23 -04:00

Joe Zeng	96ac054cf6	Stopped bottom-row garbage from clearing 5 lines. (#16 ) Resolves #15. 1) Cleared row count is marked before the onPieceLock method is called, letting the piece lock procedure react to the count of rows the piece is about to clear. (In practice, only 0 and non-0 will be different.) 2) The modes with bottom-row garbage will not advance the garbage counter when the piece is about to clear lines, as should be the case. Also included: 3) Changed the Always O Randomizer to the Always Randomizer that takes which piece it should "always" produce as an argument in the constructor. 4) Fixed the torikan for level 800 in Phantom Mania 2. It should have been 4:45, not 4:40.	2019-06-03 23:12:48 -04:00
Joe Zeng	b7fc51f4bd	Made the coding convention examples a little more expressive.	2019-06-01 23:41:36 -04:00
Joe Z	04ccd628be	Fixed up the docs.	2019-05-31 23:59:04 -04:00
