I think you have a solid base for a cool walking-simulator here! I loved the clutter of the level and the way the buildings at the boundaries bounced up and down. I think y'all did a really good job of creating distinct spaces within this level, and you could really lean into that to tell some cool stories with them if you ran with this idea.
If you do want to keep running with it, I would love for there to be more audio besides the lovely background music. I am aware that psychedelic experiences are as much acoustic as visual and tactile, and having the soundscape of the game reflect that would take this to the next level. You could also use sound to guide the player towards the collectible items.
I wish the trampoline had bounced me ;( but that's the worst thing I have to say about this. Great job!
