The game fails to run:
$ wine JAM2022_GameOff.exe
002c:err:module:import_dll Library UnityPlayer.dll (which is needed by L"Z:\\home\\quasilyte\\Downloads\\JAM2022_GameOff.exe") not found
002c:err:module:LdrInitializeThunk Importing dlls for L"Z:\\home\\quasilyte\\Downloads\\JAM2022_GameOff.exe" failed, status c0000135
It looks like it misses the UnityPlayer.dll
in its distribution.
Consider adding all necessary files to a zip archive and upload that instead.
The player would download that archive, place them on their machine and run the game from that folder.
Let me know if you have any difficulties.
