TetWiis is a Nintendo Wii Tetris clone, shamelessly based on the Nintendo DS version of Tetris. TetWiis is freeware, can be distributed freely and should never be charged for.

Changes:

– Improved Block graphics
– Added 3 in game backgrounds that change every 5 levels
– Implemented power/reset button callbacks
– Minor bug fixes
