Wow, an Android game? That's new and i like it. A very polished and fancy game, it really works amazing. I love the way you used the jam theme, very original and solid. As only complaint I think that you have to increase the difficulty, and made it faster. Until the 200 meters there is no several birds on screen, and I when I reached 550 meters I stopped playing because it seems a little repetitive (and because I thought I was going to make that breed of bird extinct hahahaha). You have a really great patches mechanic, but if I can destroy every bird is not well appreciated. With some balance fixes and some kind of new enemies you can perfectly release this game in the PlayStore, good job dude!
