Sports Ball Spin for Android

Hi all, just released my new game, Sports Ball Spin, on Google Play. If anyone has the time and inclination to take a look, I'd very much appreciate some feedback on it. It is intended as a minimalist but highly playable (hopefully) touchscreen physics game. No cutting edge anything, so if that's your thing then you probably won't be all that interested. However, I have long held the opinion that graphics and gimmicks often detract from gameplay - which is the main point of a game for me - so this is a small offering to try and redress that balance. https://play.google.com/store/apps/details?id=com.kbitretro.sportsballspin
