CACK is (or will be) a constuction kit for crap little adventure games. Think Dizzy style gameplay (pick up object, use object etc) with Zelda style top down view. Beta 2 is just a release of the player (editor has not been started yet), but you can still use it to create games if you do not mind doing a bit of manual editing of xml and writing map data. Included in the zip are GP2x and windows binaries, and full source for building on linux.
