As many other people would call this a Puzzle-Platformer. The style of the game has a 8 bit feel with a full screen support which is very nice. the game has over 54 level to complete. Only thing that is a bit of a problem is that there could have been more soundtracks. Plus the humans you capture also should have run away from you when they saw you coming for them. Other than that it is a cool game I really enjoyed playing it.

A pretty fun short platformer. The main criticism from me is the RNG side from the turrets that will shoot at you with no pattern making being killed by them annoying. If you get a 66% off discount from cards, I'd recommend.

I've only played this game a little and I am already addicted. You play a moveable slime/jelly ball (with cute face 'n all) that has the ability of possessing other people in the various encountered levels/areas, but watch out!; You need to possess the correct character (professor, military man, engineer, etc); each has their own ability that pertains to the various puzzles and platforms contained in the level. You will find yourself possessing, jumping, dodging, pushing blocks, shooting, etc to get around all the various obsticles. The levels are cleverly designed and have that feel of one more try at all times. The various levels can be somewhat on the short side but never dull. Graphics are pixel flavor, sound is so so, and music is the same throughout each "area" but the game is highly addictive. Recommended!

The concept of the game is a mash up: you play as an evil jelly who zombifies humans by possessing them. It is funny in a dark and discrete way: the authors do not try to shove jokes down your throat. Which is great. The game consists of 54 puzzles (although the first 5-ish act more as a tutorial). In each puzzle you must reach a pipe, possessing some humans on the way. Each "type" of human gives you a special ability (e.g. higher jump, push boxes, double jump). These are mostly dexterity puzzles, some require trial-and-error, basically none requires thinking. The music is very repetitive and I didn't find how to turn it off, so that was annoying. I though that there was a lack of variety in the types of humans and I'd have enjoyed more challenging puzzles (strategy-wise). The control felt weird when possessing a specific unit (soldier) because that's the only situation in which you'll need the mouse. The whole game is also rather short. In spite of the shortcomings, the playing experience is good. The game did not present anything overly frustrating and delivers more or less what you expect after watching the trailer. Achievements are right on spot and Linux port is flawless (thanks for supporting the penguin!).
