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.
Development Log
v0.1b
Initial Release: 12/6/09
I consider this release "pre-alpha", as it's not yet feature complete, but homebrew tends not to follow the typical product development cycle; thus, this is the first "beta" release.
