I definitely appreciated originality in the visuals. Game jams are made for experimentation! And this game is a great example.
That being said... needed music (any music, it's 10 minutes of searching for royalty-free stuff, and it gives a lot to the game) and better controls. Controls need to be intuitive unless you're making some giant blob of mechanics like Caves of Qud. "What is the easiest and the most intuitive way for player to do what I want them to do?" - great question I always ask yourself when designing.
I hope my feedback helps. Interesting concept and aestetics! Keep doing what you're doing :)
