I love the little guys!!! Especially that handsome sponge I wonder who is that. (For real though, thanks for including me:) )
Got passed the first 2 levels but got stuck in the third
The camera movement is a bit lacking, specifically when I go down after going up, the camera stays way too much at the top, so it makes it harder to see the little guys you control.
Besides that, I love the concept, and the art of the little guys is very cute! Nice job!
