The ideia is very good and worth exploring. Unfortunately the game needs a little more polish on the controls and variety of stages and changes to the mechanics. Ironically I kept getting upside down stages were your controls are reversed, so I really didn't have to adapt to controls changing, taking out part of the magic.

As a suggestion you should instead of just switching between platformer mechanics you could switch between three or four different genres, like in one stage you have a platformer and the next you need to solve a puzzle or talk to a NPC.

The idea is definitely a nice one and has a lot of potential, but the execution is a little lacking. Art is all around good except for the UI dialogues which couldve used something else than the default unity UI. I had to reload the game quite a few times because my character just wouldnt move anymore, but bugs are bugs I get it if you couldnt fix that in time. As someone else already said, the levels do get a tad repetitive after a few minutes (ive ran across the same dev dialogues a few times, and the only mechanical differences ive encountered are speed, direction switch and gravity switch). Still love the idea, and when the levels work they are kind of fun (though getting stuck on walls is a pain)

I found that the levels became very similar after playing for a couple minutes, But the Idea's really good.

Its a good idea and has a lot of potential.

Along with hard-locks there's collision issues and random deaths. Technically it's in a rough state, but there's the idea of a randomly generated set of BOTH levels and mechanics is definitely interesting. 

The main menu music was fantastic, although you have some collision issues with the side of platforms.
