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.
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.
