nottetris2 (tetris clone with physics)

Not Tetris 2 is the spiritual successor of the classic Tetris mixed
with physics. The result is a fun spinoff in which blocks are no longer
bound to the usual grid. Blocks can be rotated and placed at any angle,
resulting in a complete mess if not careful. And with the newest cutting
edge technology, Not tetris 2 allows line clears when the lines are
sufficiently filled. The old mode is still available for play and is
now called Stack.

Also in this version is a multiplayer mode that allows up to 2 players on
a single computer, with each having their own seperate Stack to fill. In
the Invade mode, players can bounce their blocks to their opponent's
side and save up on their own space.
