I really like the way you introduce the mechanics! It's definitely a show don't tell type of thing, which I appreciate. Great job on the music and art as well. I also like those nice quality of life improvements like the boosters at the bottom for quickly getting back to the start of the puzzle. None of the puzzles felt too long either.
If I had one suggestion it would be to make the walk speed just a _little_ faster. I almost gave up on the last puzzle because you have to walk off the last blobby dude at just the right time or running distance or something. I think a little more leniency there wouldn't take away from the challenge but would be a bit more forgiving.
