Excellent job! I agree with other comments that controls are a little floaty and wall jumping takes some getting used to. The color coming back slowly is beautiful! Sound effects are basic but appreciated. The music is amazing! I wish I could restore the music sooner so I could hear it sooner.
Have you considered having sfx as something you need to restore (just like music)? That could be a fun little touch. I think a lot of the fun from playing the game is how gradually more and more juice (and thus fun) gets added as you restore the world.
