Pretty solid game, with a mechanic that's been used before, but implemented in a quite original way and goes well with the levels. I really liked the atmosphere, even though the art is simple. Maybe a bit more indicators would have helped with some of your abilities, took me a while to figure out how to use them effectively. Also, the puzzles can be bruteforced, therefore I think it might go stale later on, unless new mechanics or content are introduced.
