Valchion is a action RPG with retro graphics and simple mechanics. It features bright, GameBoy Color-styled visuals, and a (hopefully) memorable soundtrack. It should be released for Windows, Mac OS X, and Linux. It's also being made with the Blender Game Engine, which features fast game creation and no time spent exporting to an external engine.
A boss tank that I modeled, but then went back and re-modeled from scratch to give a better feel. The knife tool in Blender's awesome for this, by the way. :)
The old version's on the left, and the new version's on the right.
