I tried playing your game but got this error.
If you are new to Godot, I will tell you what you have to change to get your game to work:
After exporting your game, you have a TumbleBee.exe AND a TumbleBee.pck file. Most of your data is stored in the .pck-File. So you need both files to make your game run.
I would recommend you to
- export your game into a new folder
- make a zip-Folder out of the Folder with your .exe and your .pck file
- Edit your game page on itch io: Remove the TumbleBee.exe from itch.io and upload your ZIP-Folder.
Hope this helps
