The game is a time waster, ideal to play if you have 10-15 minutes with nothing to do. The squash and stretch makes the game feel a lot better and with the health pickups and endless jump at the cost of your score (which, by the way, is a cool interpretation of the theme "Less is More") there definitely is a learning curve. Speaking of learning, the controls are easy to learn, after a few rounds you know exactly where your jump will lead you, and the mechanics are conveyed well. Black birds are fast, white birds are a little slower, you lose health when a bird reaches the left side and you can jump at the cot of 10 score. 

All in all this is a very solid game, would be publishable on a phone without too may changes.

Congrats on this project!
