Incredibly unique and thoughtfully designed. I felt like I was both playing a challenging puzzle game and moving around inside a work of art simultaneously. I can't wait for more levels and for more releases from dest1337. 

Really solid idea and the UI all looks great. The only thing I'd change before adding more levels is the gravity. Felt a bit slow to me, and I would have appreciated a slightly higher jump that fell quicker. And not sure the sword is necessary, though it'd be awesome if later levels involved fighting off color monsters that are hidden in some colors and exposed in others.
