Previous Comment is right,
the exported game should be a .zip folder with all the folders Unity provided next to the .exe
So inside the .zip should be the following files: (Assuming your game name is "Inkio")
- Inkio_Data
- MonoBleedingEdge
- Inkio.exe
- UnityPlayer.dll
- UnityCrashHandler64.exe
I hope this helps you for future GameJams!
