It's a unique experience with unique controls for a unique character.
Gameplay
Yummy: The game has a unique feel compared to other 2D platformers. The objective to get the other stupid looking character his bugs is a unique idea. There is so much to do that keeps you playing this game longer.
Gross: Controls can get frustrating, especially trying to nail down the difference between sticking your tongue out and leaping. Sloth or whatever his name is should get his own food. Jerk.
Sound
Yummy: Tracks are pretty catchy. Sound effects are fun and random.
Gross: Hearing the death song over and over.
Graphics
Yummy: Really smooth graphics. Backgrounds are pretty detailed. Great theme with good tone in colors.
Gross: Character is small. Sometimes you cannot distinguish if a bug is poisonish or not.
Multiplayer
Yummy: Good variety of modes.
Gross: Don't wanna play it much. No one else does either.
Overall
It's a great game. It's unique, aside from Mario and Sonic. The controls may take some time to get used to, but once you nail it down, you'll like the millions of puzzles this game has to offer.
