Yeah, don't bother with this.
I picked it up today and it's going back tomorrow. The background and foreground blend way too much together, and the levels are just swamped with monsters. More often then not I found myself getting hit because of something I couldn't even see or falling down a hole I didn't know existed. There are even 1-hit kill monsters that in no way suggest that their even enemies, so cheap deaths seem to happen a lot. Everything is a colorful mix of garbage thrown together. There is no distinguishing between things in the game.
On top of that, the level design is just atrocious. The goal is to pick up every red blob in every level, but their locations feel completely haphazard and poorly thought out. There seemed to be whole sections of levels I didn't even need to explore because there were no blobs located there.
The game also has a floating mechanic, which pretty much completely invalidates any sort of platforming challenge to the game. Instead it's almost just a mad scramble of a level with dozens of badguys attacking you from every direction and some lame combat that will get boring before the 10th level.
It's not worth $8, but much more importantly it's not worth 5-12 hours of your time.
