Only tried the first couple of tutorial levels, but I kinda dig it. With the music, it's a soothing little game. Not sure how the rest of it will play out, though. The touch-screen control ain't perfect -- Shard doesn't move with much finesse -- but everything seems to work fine. The graphics are a bit rough, but it's not an ugly game or anything; it just looks like early 3D graphics -- something along the lines of Deep Labyrinth. Worth a try for folks who enjoyed Starfox Command, I think.
