Thank you! This was my first experience designing a bunch of levels for a puzzle game, so it went surprisingly well (I did make sure to playtest early, that really helped).
I learned rather quickly that levels had to be heavily constrained to prevent everything from becoming too confusing, but as a side effect there’s not much room to play around with the book! I actually added the more open early level with a bunch of water pools after someone noted how tight the levels feel.
