Saw Mark play this on stream! The puzzle mechanics in this are really really good, and the visuals are so unique and go well with it. Putting the level number on the rock was a new idea, and that was pretty cool. The gameplay is simple and easy to learn, and you're great at this puzzle design.
Only thing I would say, though probably because I'm dumb was that some of the puzzles were a bit unclear as to where to go and what to do. Some little visual indicators like particles and glow, or have the level sort of "move" towards it would be a very nice touch.
All in all, excellent submission. I would love to see this expanded upon!
