Very cool puzzle game ! The game play is very intuitive and no need long explaination text to give us the mechanics, all was done by thoughtful level design, very well done. On top of that it has a satisfying end, you manage what we didn't, make it short enough for a game jam xD
I feel some level could have been using more combination of the unseen power. But it's already very good. I also really liked the graphics and the music. The aesthetic is well polished.
Great job!
