It's definitely one of the most polished game of the jam. It looks and feels like a finished game, with an incredible amount of content. Just amazing work, you're definitely going to the top 100, and most likely to top 20 !
The only thing I see a little bit lacking is the pacing, it felt like most of the levels just played themselves and I only were a spectator, the next step always felt obvious, which is great for tutorial levels, but not for the whole game. The only moment where it felt different is on the very last levels, where while the levels still felt a bit on rails, the purple gas mechanic felt a bit too frustrating, as it allowed absolutely no error. But the very last level was really enjoyable, it forced improvisation in a way no other level did. And the boss is really too punishing to be fun.
