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 basic block that you can shoot to move in certain directions. This is going to be a part of the puzzles available in the sewers area (at least, that's the plan).
