You got a very good idea and concept, but ultimately failed to implement it correctly. Either I'm not understanding something, or the background elements of the second level don't actually match with what you encounter after the moveloop, there are some spikes that weren't there before. Also, you should try to avoid long empty spaces in your levels, they are quite boring to get through.
If you do want to expand upon this idea, go ahead, I believe this has a lot of potential, but in its current state it's really hard to play
