Sorry. Maybe you downloaded 32 bit on 64 bit, or reverse. I couldn't find the way to upload both windows binaries to itch.io without one of them overwriting the other.
I will upload a new binary when the jam judging is over. If you are a judge, take into account I uploaded this because someone asked me to upload even if it was a fail, but giving me 0 points in all categories would be right. This project is incomplete and barely works.
