CanCan has posted news of the release of his new game written in Lua for the PSP, heres the info:
Vexed is a puzzle game in which your goal is to move similar blocks together, which causes them to disappear. Block can be moved to the left or to the right. When no block in under the current block, the block falls down.
Once all the blocks are gone, you've solved the level and you're presented with a new level to solve. You can only access the next level when the current one is solved. Vexed was created by James McCombe (Vexed at SourceForge.net) for the Palm OS.
