The demo is finished, and I wanted to release it tomorrow, but for some reason I don't understand, I'm now seeing this:

Now GameJolt won't let me upload the game, nor will it let me add the music to the page, and I wanted to add two new tracks I made. This must obviously be a server error or something similar,

but until they fix that, I won't be able to upload the game to this page

This might have delayed the demo, but I remembered that I have an itch.io account, so I think I’ll upload the demo to itch.io
