Controls need a lot of work. Forcing the player to restart for dying too many times is not necessary in any game these days. Especially since I don't remember seeing anything that warned me it would happen. Fix the typos!

Just a few thoughts. It's an interesting idea, but there's so much going on that you can't really meaningfully predict where the bubbles are going to be, so each shot just kinds of ends up being random luck. Also, when you hit a red bubble, don't force the player to restart, just load up a new screen.

Just a heads up, level 3 is really easy to cheat. Just jump while hitting a green thing and move to the right.
