Enjoyment: At first, I thought it was just a basic platformer. Metamorphosing and playing the level again was a neat touch.
Concept: There were some really cool ideas. Having one guy jump over spikes and another dash past them is a great way to reuse a level.
Presentation: While I liked the goofy frogs and their distorted animations, the game-feel is my main problem with this game. I got stuck on geometry a lot, which is frustrating.
Use of the Limitation: Again, running three characters with different movesets through the same level is a really neat take on the limitation. The fact that it ties into the life cycle of a frog (tadpole -> frogline -> frog -> hench frog in top hat, right?) is even better.
