I liked the platformer. Liked the idea of having to be active and with the colour swaps. It did end up costing me a life a few times but feels like a good skill based mechanic.
Some of the leaps of faith were a bit frustrating since you wouldn't know which direction to go to. Having said that, personally I liked having to jump and figure out where the plaform is by failing. And then slowly getting to build up a picture of the level that way.
The only thing for me would be to have a some sort of indicator in which direction I should go at the start of the level.
