Rock solid platformer, I'm always a sucker for floaty ass jumps and they feel great with the player scaling - which is a rock solid mechanic, higher jumps on larger sizes make the puzzle goals clear
That said, I think I didn't find myself engaging with the scaling mechanic that much beyond finding secrets - When engaging with the main puzzles I found myself only worrying about which switches were toggled, the scale crystals felt like a means to get from point A to point B. I think more emphasis on the scaling would've been great to see, but beyond that, this is a fun game.
