Funny little rage game, but i have some things you could improve:
1. A main menu is optional, but it would be great.
2. ADD A TUTORIAL! I didn´t know what to do before i read the description.
3. The graphics aren´t bad, but maybe try to root for something more blocky than "i drew this in paint ms".
4. I have an idea: When i first saw this yellow ball, i thought, if you position the two characters the right way, the yellow ball could shoot at the enemies! That wasn´t the case, but i think it would be supercool.
I hope the feedback helped you, would be nice if you could check out my submission too. :)
