Thank you so much for your detailed feedback it is beyond appreciated!
I just took a look at the code and the ghost dying to spikes was a silly error and easy fix luckily, so I'm going to release a post-jam patch with that in a couple weeks along with more settings to tune in the lobby.
I'm so glad you found it the loop enjoyable once all the technical issues were sorted out! I still have plenty of interesting ideas for the design so if I ever get a good opportunity I would love to make this into more fleshed out game. :)
