The mechanic of having each character have different abilities and switching on-the-fly works really well! The dash is fun to use but smartly limited by not being able to jump.
I did have a lot of trouble with the final level, as the platforming required some fast inputs, but I did beat it in the end. I'd love to see more done with these mechanics!
Specifically some more puzzle-oriented levels (how do I get from X to Y with the moves I have?) rather than precision, as that was the part I had most trouble with.
