It is a good game. The music fits very well. I like the simple graphics, I think it would nice if you made the player squashes when it's moving fast. The fast enemies I think that they are too fast, it's pretty difficult to predict if you will collide. Also the UI to replay could be better. You can also make the combo text to fade out smoothly instead of just disappearing.
Even if it has things that can be done better, it is still a great game.
