Great puzzle game that manages to infuse both themes into the core gameplay. Difficulty curve felt good and steady introduction of mechanics was well done. One exception was level 3, which I ended up skipping, despite finishing the next 7-8 puzzles. Probably not a real difficulty problem, I'm just missing the key insight to solve the problem, could you give a hint?

An excellent puzzle game! Really had to stop and think for some of those later levels. I can tell a lot of thought and work went into the level design 😄

The implementation of the theme was really nicely woven into the puzzle mechanics and design too. Having the checkpoints effectively transform the level layout based on how you move around, and having to plan ahead to cross back over your path is super cool.

I really appreciate the skip level button too, as I had to leave and come back, and was able to continue where I left off using that 😃

An undo button is only feedback suggestion I had in mind, and can see that's already been addressed in other comments.

Great submission!

Really cool, and very difficult game! I really enjoyed it! The one thing that would make it perfect would be an undo button! Also, even though the style is great, the 4 tone color scheme kinda makes objects difficult to parse in the later levels. 

Nice puzzles, however whatever the theme may be I seem to stumble upon games like these in any jams(That is not a bad thing tho, since yours is very polished). Nice polish, nice sound effects and art, good job!
