Very nice game
I liked the style and music, they fitted each other perfectly, the graphics were cleanand fit well. Actually I've seen only one little trouble with the graphics, namely the firecracker; when it goes up, the clockface on it becomes invisible. Violence was good too, I liked the explosion when you get rid of the rocks and the splash when a wooden log falls onto the ball. Humor it certainly has, and interactivity was great. There were so many things to push that it did get a bit confusing at first, but luckily the levels are arranged so that you build up the knowledge on what to push for which object.
There is a way to make it harder, which would be using with different colors, like you can see in the game Marvin Spectrum here at NG. That's really hard because you have to use both sides of your brain at the same time.
Furter, I did at a point get the idea to just mash all buttons to get past objects, but no dice because certain object (like the spikes) came back if you pushed the opposite button. I liked that very much, good way of forcing someone to not cheat like that :)
