I'd do it myself if I knew how. I don't have the project structure or an editor for godot. (Notepad++ is okay for some edits, but not efficient).
I would have no way to ensure I didn't break anything, besides running strive with the edited files. (which is a crappy way to test code).
If I already knew the code in detail, adding a pony race would take me less than an hour I estimate. (correct me if I'm wrong, people who actually make the code).
