Eh, where to start?
Well, beside character moving too slow, there is obvious lack of the "continue game" option at the menu.
After you beat the boss that requires the megaphone, during the cutscene I clicked "x", which of course ended with the character falling to death, but the level didn't restart, which meant that I had to play this crappy game all over again, because, again, no continue option.
In sewers, during one of the jumps, the game just stopped responding, and the character stuck in mid-air. Crash, glitch, bug, whatever, I said "fuck it", not going to play all this shit over again.
Humor is okay, graphics are crude, and I turned off the speaker (mute button would be nice)
It's nice that you tried to make levels different and not repetitive. All in all the game is not hard, but it would be nice if you polished it, and followed cyberdevil's advice. And who knows, you might be a great gamemaker someday (but you have to grow some mustache first, if you know what I'm saying)?
