Not a bad idea with the way level swaps between two variants on jump, but there are two problems with the implementation that makes it really hard to judge and enjoy the game. One are the controls - I think being able to control the character in the air would do a lot of good. The other thing is the jump and fall feel to be be very slow, so if you misjudge the jump you have to wait until the character lands before you can try again. The other issue is that while dark platforms had an indicator where they would appear, the light ones lack that feature.

But it's not a bad idea at its core, just needs a bit more polishing before it could be taken any further.
