Like Jay said, this idea is strong and I can see it's potential. With some iteration and polish this game could really work well!

I really like the idea, it makes for an interesting puzzle platformer that really forces you to think before you take actions.  With some polish it could turn out to be a really solid game.  There were a few issues I encountered such as inconsistent collision (ie stopping because I touched a wall or ceiling) that due to the nature of the puzzles could make you mess up your jump or worse drop you to your death.   One possible other improvement that might help would be to have the inactive color's obstacles still shown as an out line or very faint.
