Oh, this definitely worked for me. Completed the game. Controls could be a bit tighter for a platformer, feels a bit floaty.
The gravity rotation and time rewind are both fun mechanics. I think you could have left out the 10 health, that would make the time rewind more important.
My 4 year old that was watching wanted to see more levels.
The Art is good. Music got a bit on my nerves quite quickly.
