It's fun enough. It controls pretty well and looks nice, but the music is fairly generic. The first half of the game is pretty fun, and has a lot of variety. The second half is much less good. The lava world has a huge difficulty spike and obnoxious obstacles. The water world is just 4 levels of boring auto scrollers. The last world is alright, but not as tight and varied as the first three. The bosses are all pretty boring. Overall, pretty alright.
