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.
I'm working on this boss while I'm making maps and stuff - it's going pretty well so far.
