TetriCycle is Tetris projected onto a cylindrical surface. Rotate the cylinder left/right such that the descending piece falls into place. TetriCycle is freeware, can be distributed freely and should never be charged for.

Changes:

Added sound FX.
Added powerups to multiplayer. Please enjoy!
This game will be open sourced soon, at which point you can add your own powerups.
