A very good brain teaser packed with a ever growing in complexity set of puzzles, though not before teaching you the different techniques you'll need to get through said puzzles. Great design! Also nice humor with the tutorial and the little characters, just a nice puzzle game to sit down and burn your brain with a bit. Can't think of anything to fault it, I could see this being a priced game on a mobile device, would be nice to take it out and solve a puzzle or two when you're out and about.
If you have time, would love to hear what you think of my game; https://itch.io/jam/gmtk-2019/rate/461074
