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.
Working on the sewer map - you can see the map's made of individual tiles, as well as what it looks like in-game.
