I realized you uploaded this and I couldn't find it for a while. I just realized you didn't actually add a mode on this at all. No one can look at this level without manually adding the level file to the MyLevels folder so they can open it in the editor.
That might be what you intended, but most people don't know how to do this. Usually people learn how to do stuff by asking in the Distance Discord or something. (cool place btw you should join it if you haven't lmao.
