Really cool game overall! Just played the first few levels and had a blast. I think the gameplay is really interesting and the characters have a lot of charm for a ball. Love the squash and stretch.
I think it could probably use some more graphic updates. I had some trouble seeing the blue switches and some of the projectiles. I also think it could have an easier introduction. It gets pretty hard on the first level and it took me a while to realize I could wall jump. Also I feel that there's more here. I can see how "Trip" could open doors or create platforms for trap. Doesn't have to be all negative!
Definitely a cool concept!
