Amoebax is a free Puyo Puyo-style puzzle game for up to two players. The objective of the game is to beat the opponent in a battle by filling up their grid up to the top with garbage.

The game is still in early development stages, but binaries will be available for Microsoft Windows, GNU/Linux, Mac OS X and GP2X. Since Amoebax is free software, the source code is also available.

Version 0.1.1 (2007-03-11)

Added normal mode with six AI players.

Substituted placeholder graphics with sweet new graphics.

Fixed some minor bugs.
