Reaaally really cool game ! I love it ! Here is why :
The game in itself is beautiful and the controls are easy to understand. The game has 4 different difficulties at the moment and has vibrant graphics. When playing there are 2 different types of arrows, and they can come slow or fast.
But :
The game is quickly finished as it lacks of content (the easiest way to change that would be by adding the possibility to create levels (I'd love to do that <3) or skinning the game) Also, would be interesting if there were more types of arrows (accelerating, going in a random direction or switching approach line clockwise) .
Yet this game is probably in my top 5 of rhythm games, even if it has a short lifetime.
