Hi, I'm glad you enjoyed the game.
It's been a long time since I published it and I don't remember very well why the map isn't working.
I had a look at the gameJolt version and what I had implemented for the map works there.

I also don't remember if it's the same version on both platforms because I ended up losing my log in to gameJolt. There is a chance the gameJolt version is newer.
I'll take a look at the files I have and try to make a fresh build for itch.io
