Nice game. Took me a while to understand how to pass the blue puzzle.
The only complaints I have is that the ressonance's center is a little bit upwards (if you ressonate below a wall nothing happens, for example) and that I had to restart the puzzle all over again sometimes, moving all the pieces again, maybe having the pieces reset after some time and having a cooldown for the ressonance would work better.
Anyways, had fun playing it! Congratulations on the game!
