This is a fun little prototype! Instead of bringing this to a "playable" state, I think you should move on to the next game jam and create a new project. You will gain even more experience that way, and also get feedback every time.
I agree with the above ^^
World generation like this is a neat tool to have in your bag of game dev tricks. :)
I would take what you learned here, and bring it with you to the next game jam. Congrats on your submission!
