Nice, glad to see more content from you, your characters have been really unique so far. I won't jinx things so knock on wood, but there is a couple pretty simple things you will need to do in the next version to port them over, but it's mostly just redoing the borders around the sprite like you did in this version with the new system. I'll put up a small guide on porting mods here when that version becomes public.
Looking forward to seeing your mods continue to grow!
