Nice idea and I really like this distorting shader :) really nice game and a good take on the jam topic! My advice would be to make it either less arcady and more puzzle-driven or vice-versa.
'Cause as of now I'd say the character's not responsive enough for arcade, at the same time the hazards are a bit too arcady and analogous as for puzzle (by that I mean you do not see the exact pass you have to take, and you need also to get the right timing, I'd leave the timing only for now, and make corridors' cellular for you to see where hazards pass).
Nonetheless, the game is very nice! Congrats on that!
