I like that you've got different characters to choose from, each with its own set of levels! Adds a lot of replayability.
Sometimes it was a bit difficult to really explore the levels, though - sometimes, especially in the case of playing as Red, there were drops where I couldn't see on what I would land. I think zooming out the camera would help?
It was still fun to play, though - exploring each character's ability throughout the levels was good!
