Very fun, you could totally release this as is on mobile. It has that great mixture of being super easy to grasp yet challenging enough to keep you engage. I spent over 25minutes trying to get a high score. (Mine as of now is 9)
Presentation wise I have no comments or critiques, it looked and sounded excellent, and remained very readable which for a game like this is of the upmost importance.
Sorry i don't have any constructive criticism. I may revisit this after a good nights sleep.
Great Work
