got a lot of gun upgrades really quick, then didn't see any for a while. Maybe making them a bit rarer or adding more levels of guns would help with that? Otherwise this game is great, especially for a first game. 5/5 and keep up the good work
I think an "instructions" would be a good idea. Maybe a tutorial? I didn't know you could move until I died and was rating it and noticed it in the "about" section.
I think the expression "Go out with a bang" has a lot of meaning in flash games. Although having similar levels for the end was cool, maybe just 2 would have sufficed. And another, *different* level to end with would have been nice. Perhaps a really easy one that looks really cool. 4/5 anyways, very entertaining.
