The fact I could go off screen and it seemed to cause the game to not really work anymore was an issue. I liked the different enemies. I think a few more powerups and more difficult enemies would have helped. A simple fire sound, and grunt from anger would have added a lot. Adding a high score also would help, so you keep trying to develop more games.
wow, I did not see this problem, I will investigate, I made the limits when there was little time.
Thanks for the suggestions! I recorded some sound effects but that was when i did not have time enough and i was afraid that they seems very annoying and spoil the experience.
I will implement high score and sounds later :))
