Love the idea of traversing the levels in your dream as well in order to unlock certain areas and change things. We actually had a similar idea with that. I really appreciate that, although the players physical position gets reset on death, any progress or changes in the level do not. That was really nice. I got pretty far but unfortunately, at some point my character glitched into the floor and I wasn't able to move or sleep so I had to stop. I think the levels were pretty interesting and used the mechanic in a nice variety of ways to where it didn't get boring. The wall jumping seemed a little inconsistent which was probably my biggest frustration I ran into. I couldn't tell if I was meant to do a tic-tac back and forth, or just spam up one side. Sometimes one worked, sometimes the other. Also, sometimes I would just be able to jump much further in my dream than normal, I wasn't too sure why. I was able to do it on purpose sometimes and solved a few levels with it, so maybe it's intentional. I really enjoyed the level where I had to push myself past the walls, and then the one where I pushed myself through the spikes and Z's. I think there is a ton of potential in this idea and I hope you keep going with it. Overall though, I think is a pretty good game with a nice core gameplay loop. A bit of polishing and this could be really great. Well done!
