Polygonauts

We know that your video-card handles thousands of polygons per second, but can you take care of a single polygon lost in a bizarre land, far away from home? Polygonauts is a 2D adventure/platformer indie game for PC (Linux, Windows) presented in neat 2D graphics. Prepare yourself to control a wandering meta-morphing polygon who's in deep trouble and has fight its way in an exotic island in order to return to safety and, with a little luck, avoid the mysterious Dark Sky phenomenon!
