Fantastic visuals combined with great sound design makes this a lovely experience. It's a fantastic take on the jam's theme and handles really well!
The one issue I bumped into was losing direction at times. There were a few points where I was not sure what exactly I should be doing and assumed I was just stuck before double jumping blind and working it out. Perhaps adding some form of very light illuminated moss or scratches on the back wall showing possible places to look would be great for guiding attention without taking away from the atmosphere, difficulty, or exploration :)
I really loved this one mechanically and could see it fleshed out into a full experience, fantastic job!
EDIT: By the way, the 37s before deadline must have been crazy stressful, good job sticking it out and making it in!
