ThatOtherDev started making a new homebrew PS3 game, currently named “The Unmapped Forest”. It will be an action RPG game but it is in very early development stages. It currently consists of a forest that you can wander around in and some slime monsters that will follow you. You can attack but you can not actually hurt the monsters and they can not hurt you.

There will be PC and Wii versions later.
