Oh it's neat that someone tried it out so long after I made it, thanks.
This was my first game jam I ever did, and solo at that. It was a pretty hectic learning experience. No fullscreen available, and actually no sound in the game. For submission I don't think there was an option to say "no audio".
If you want to try it, hit enter when loading up the game, you'll enter a placement mode where you can place demons in select spots, and then you'll be able to move around to the exit. I'll see if I can edit the page for the game but don't think I was able to since it was a jam submission.
