Nice and simple

Simple game but entertaining. One thing i'd change is the reliance on the mouse to change levels. Alot of the time i was crashing because i didn't get back to the keyboard quick enough

Humorous

I found Bob the button quite witty. You could probably turn it into a puzzle quite easily like someone has done with the red button. Maybe make it more like a game as opposed to a flash movie.

Stolen

If you are going to make a game try not stealing it from somebody else. This is a ripoff of Kongregate's Shootorial. You could have at least added some originality to it. Lame!
