This is very good! Another winner contender I might say. I wholeheartedly think that with some minor adjustments and a bit more content, you could really sell this on Steam! It just got the quality and polishing needed for a successful puzzle game. I like the puzzles very much! It's not too difficult but is never a no-brainer, and it does get a bit more complex in the later levels. I also like how you slowing easing in the different puzzle elements so that we are not overwhelmed by all of them. Overall, I'd say this is a very nice game!
Normally, I will try to give constructive criticisms for every game I've played, but I can't really think of any when playing your game. The story is probably a bit too short and vague, but this jam only lasted for a week, so it's already too much to ask for, given that there are a lot content in the game.
Anyway, this is very well done! It's now one of my personal favourites.
