I have just tried: something else is missing.
Error
Data folder not found
Details:
Application folder: C:/Users/[…]/AppData/Roaming/itch/apps/library-roll
There should be 'GMTKGameJam2022_Data' folder next to the executable
I think you should bundle everything needed (there may be a lot of files) under a ZIP file, and then upload this single ZIP file for download.
What files are necessary should be given to you through some Unity build process; I do not use Unity personally, but this may be said in some helping section of the software, or alternatively, ask for help. I would recommend contacting the game jam team as quickly as possible and explain the situation.
