Really creative vision and great execution, I would have just a few suggestions:
the controls are not very intuitive, but I think a simple way to make it a bit better would be to use the arrow keys instead of ijkl, since ijkl is such an unintuitive control scheme. There are probably ways to make it even more easy to pick up but this is my simple suggestions
and the second would be to not use red for positive things. After the first level I immediately forgot that red were jumping platforms and avoided them until like the 5th level. Its always important to use preexisting familiarities, in most games red is bad, so red should mostly be used for something that is bad (like the enemies)
But despite those complaints, great idea!
