I had so much fun with the distinct characteristics of each environment and the puzzle elements built around them!
The puzzles in the water stage were grand and challenging, but the sense of satisfaction when I solved them was great.
I also liked how many of the orbs had sharper, more specialized properties than I expected—it was really interesting.
I especially love things like the glass orb that shatters when you fall, despite that drawback! (=ↀωↀ=)
