Interlopers are live! They're actually pretty finicky so if you don't like them, I included a site-wide toggle in the animal widget. Spawn rates, animal sizes, track placement, whatever, if something looks irritatingly wrong, it can be fixed! It's supposed to be a silly background event but I found myself getting oddly particular about it.
Love it :)
I just realized I didn't update my style.css so the interlopers will go BEHIND everything as soon as I get home
