This game is really well made, and it's a fun arcade game with some really good music.
There's not very much content though, and while it does take a lot of practice to beat the game, you'll probably find that most of the time is just practicing the last level, because the other ones are all easy compared to that one. Actually the last one is kinda unfair I'd say. But anyways, it's still a great arcade game that's fun for a while.
