This is a rhythm game revolved around base jumping; It comes with some of its own quirky songs or you can play your own. It seems to be stuck in what I'd call Developer Limbo-- That, or the development for this game is agonizingly slow. While the concept is an interesting one, gameplay still has a very barebones feel to it and there are bugs to iron out still (It failed to load the song on the first level for me when I started the game for the first time.) You can still get a fair amount of gameplay out of it regardless but I'd pass this up unless you're a die-hard fan of rhythm games.
I reccomend their other game (AaaaaAAaaaAAAaaAAAAaAAAAA!!!) instead for a more finished product-- Albeit without the music element to it.
