- Use A,S,D,W(Player 1) and Arrow Keys(Player 2).
- Play with a partner or play alone by using both hands on the keyboard.
- No sound.
If you drop your piece on your partner's piece or if your partner's piece drops on your piece, it'll stay stationary just like as if you would drop a piece on bottom of playing field, so stay out of each other's way is a good idea.
Also if you play too fast compared to your partner and you build up your side of the board you'll have less room/time to maneuver your piece so try and stay somewhat in synch.
Pieces will drop faster as you and your partner destroy rows, Tetrises are encouraged because the timer will decrease the same amount each time a row (2,3, or 4 rows(tetris)) is destroyed meaning the timer will decrease by 10ms for a single row and will also decrease by 10ms for a Tetris (4 rows destroyed at once).
post #6 below has joystick support for player1 on Wine/Windows. Follow my the link in my signature, it has the latest Windows executable which changes background music and background image.
