Solid take on the mirror-movement type of puzzle game. There were so many levels, I didn't make it through them all but I definitely played more than 10. Level/Puzzle design was pretty good. Decent difficulty curve throughout. Some feedback there: some levels don't have border walls so you can walk out of the screen. Also not a huge fan of sand potentially shifting you into a wall and soft locking the level, though its not the end of the world with the ability to instantly reset the level. Although sand also led to some scenarios where I could cheat the intended puzzle by just getting lucky with where it places me.
I liked the music a lot and multiple tracks a was a nice surprise. But I liked the sfx less. Ice collide sound a little annoying since I pushed people against the ice to solve puzzles. Same with switch sound it's just a little too loud and frequent. For the art, characters look solid but the tiles could be better.
Overall a good game, I had fun playing.
