Very, very boring. You get to click, and while you're clicking, you get to do so many things! You get to collect cans! And avoid spikes! And saws! I know I'm not supposed to bitch about why games make front page, but this is ridiculous.
This game has annoying 16-bit-esque music coupled with a colour scheme that is really hard on the eyes. There is quite simply no reason to play this game; there's no compelling story (hell, there's NO story), there's no compelling graphics, and there is basically no engaging reward system. Medals? Whoever stays for the medals has too much time on their hands.
I'd recommend watching Leo & Satan III ten times in a row, it's much more rewarding.
