TODO: Do this in Scala and make tetromino generation cleaner
Tetris is played by maneuvering geometric shapes called "tetrominos" as they fall down the "matrix." A tetromino consists of four square blocks, and the matrix is a playing field that is 10 blocks wide by 20 blocks high. The objective of the game is to manipulate these tetrominos to create a horizontal line of ten blocks spanning the matrix without gaps. When such a line is created, it disappears, and the blocks above will shift to take their new places. When a certain number of lines are "cleared", the game enters a new level. As the game progresses, each level causes the tetrominos to fall faster, and the game ends when the stack of tetrominos reaches the top of the playing field and no new tetrominos are able to enter. In this implementation, completing 15 levels is a player victory.
- Hold button
- Queue preview
- SRS (Super Rotation System scheme) implementation (floor and wall kicks)
- Randomization per 7-piece bag (interesting implementation)
- Scoring and line clearing closely emulates Tetris Marathon mode
- No distinction between Mini and non-Mini T-Spins since lame factor
- Tetromino sprites
- Elapsed time
- Lines cleared
- Used custom font file
- Game pause on focus loss
