Pufftris

Pufftris plays like the original Tetris game, where you must carefully rotate and position falling pieces to complete horizontal lines. The main gimmick is that as you play, the dropzone will start swinging around, and as time passes it swings around more and more until it almost becomes nauseating to continue playing. (The authors themselves say "Don't blame be if you get seasick!".) Definitely a neat effect but hard to actually play! This game was apparently made for a Tetris-game competition of some sort and won second place.
