fun game, but could use a few inprovements
Overall, I thought it was a good game. It wasn't too harsh for those who just want to enjoy the game and pass the level, but at the same time it has a high score table to encourage people to take risks and stake their claim at the top of the board. The controls are nice and responsive (although they are a bit sluggish,) and the style of the flash fits the whole theme of the game perfectly.
However, there are several improvements that I think you could make to this game. First off, I think that the collision detection is a bit unforgiving. It claimed that I bumped into several obstacles even though I didn't. Second, it seems like the notes appear randomly on each level (although sometimes I can see where it's synced up to the song, but not all that often.) Maybe you can make some flashes at the right side of the screen (that are similar to the flashes surrounding the good notes) to show how the notes are synced up to the song, or something like that. Additionally, I found that the music at the title screen gets all messed up if you view the credits.
Also (this is just me nitpicking) I feel that the title screen takes way too long to come up because the words come up too slowly. Even so, I think that this is a good game and, with some improvements, could be something awesome to behold. =)
