I agree with you. I started with BB3 and as soon as I tested BB2 I switched to it and barely use BB3. I've also seen problems with 2D BB3, when you add a lot of objects some stop showing up. Nice work on the game by the way, I am working on a platformer myself and know how much time level design needs. I could tell that you've put a lot of time into this! Publish your games on Amazon. Admob now supports it and you might get more downloads there than Google Play because your app will be more visible to search.
