Things I like
Clever premise
Very polished presentation.
The start menu and sprites are all very nice.
The game explains its mechanics so its easy to figure out.
First two levels seemed like good tutorial introductions.
Potential Improvements
The controls seemed a bit glitchy for me. Some of my inputs (especially when jumping) seemed to be ignored. Are you checking for input during FixedUpdate?
We need more levels to finish up the epic plot!
