Very early version, pretty bare bones although all the basic functionality is implemented. There's some really really weird input lag when you first launch the game but it gets better. Inspired greatly by the actual Not Tetris. Have fun! Please report bugs/problems/suggestions to me, thanks. Now open sourced. Feel free to take and use.
Arrow keys + Z/X to rotate
WASD + J/K to rotate
The blocks way on the left are indicators. Once they light up orange, it means that line will be cleared when you land another piece. Bottom right piece is the next piece.
