Thanks for letting me know.
I have put the UnityPlayer.dll file available for download at: http://knart.no/media/
Can you try downloading the dll and try again?

I will try right now, but you should absolutely contact the game jam team again, as the rules clearly state that you need to include all necessary files on the site! Letting you know just to help you as soon as possible.
You can not require the user to download additional software from external sources (so no ROMs for emulators, or games for Roblox. If your game requires additional files (like DLLs) they should be included in the download and not require separate installation).
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.
