I can't add a lot to previous comments, just voting up that bullet is very difficult to catch which is annoying. Checkpoint system imho should work after you catch your bullet because otherwise personally (and i think many others) i'm losing motivation to play because i have to repeat same things again and again. Also i think would be better to not have so low gravity because sometimes i wanted to catch bullet midair and this way i have like only one try to do jump right... Either way very original idea, audio (except arlarm sound) and visuals (that only gun shadow tho :) ) are really good, nice game overall!
