Do you happen to have the PCK file that comes with the executable? Unfortunately, this game is not playable without it.
I found it, but I'm afraid I couldn't upload it to the game jam page
so I made a new page with just the pack file, sorry about that, I didn't realize I needed it initially cause the exe just ran on my computer
