Well, It seems I uploaded the wrong file. I just wrote an entry on the devlog explaining it. Since I can not fix it until the jam jury ends, I had removed the binaries from the download page.
That's a shame. You could try contacting the jam runners on Discord to see if they will let you upload the proper file. I saw that they unblocked the uploads for someone who needed to fix their game because it wasn't playing audio.
I just uploaded the game because someone said me to do it, but it was too unstable. I think I will upload *device-independent* jar files at github with the jam deadline state of the files, and, after a week or two, I'll upload the finished files.
