This is one of the best original games made for the GP2X, and I played a lot of it. There's so much more to the game that one screenshot doesn't show, all sorts of nifty menu animations, music, built-in level editor, multiple levelsets. So I highly recommend all you GCW users check it out!
Congrats, Mindless! And BTW to everyone, this is the same author that wrote the O2XIV image viewer used in your firmware, which was originally large contribution of his to the Open2X community firmware of the GP2X.
