I think it can be quite hard to create a mod in the editor if you are not used to it. Because of that I have created a Steam group dedicated to everything about the editor where you can post your questions. I hope I can answer your questions about the map editor and maybe some other creators are willing to share their knowledge too.

If you want to join the steam group, you can either search for "Pummel Party Modding Community" or use the link:
