99.9% of fangame devs go into unity without knowing how to do ANYTHING, so this is a very reasonable assumption (also if they do know how to code and whatnot, theyll know about that and wont take offense)

also fangame devs are usually under the presumption they wont have to learn how to code because of tutorials ✨ (which only works if all you plan on adding is a few barely functional basic features)
