I got this game from a random drawing, it looks like the upload only included the .exe and not all the files needed for someone to play the build.
The one piece of advice I'll give you for these jams is make sure you're testing a packaged version of the game as well and not just what's in your editor. You'd be surprised how often you run into bugs that only exist in a packaged build and you'll catch things like missing files when you go to try the game with exactly what we'll download and it doesn't work. If you upload a fixed version, please ping me I'd love to give you some feedback on the game!
