This game is a very underrated submission.
I love the idea that you have the same level twice, which differ only slightly, but they can also interact with each other. I would love to see more level and that you make even more interesting stuff with this mechanic.
The only problem i had is, that if you fall down somewhere you get into a softlock. But you already mentioned that on your game page. I hope you will fix this in an after jam patch, then i'll definitely play it again.
The overall presentation is gorgeous. I love the transition between the two worlds!
All in all, i think this is an awesome submission. Great work!
