I understand. Like I said, what you've done so far is very impressive. For me, these were the only tell-tale signs that this was a fan game. I hope I didn't make you feel discouraged.
On a technical level, the things I mentioned seemed easily fixable to me, but then again, I haven't seen the source code. By the way, you might wanna look up IL2CPP. For your sake, I won't get into details in a public comment section.
Anyway, I will watch this project progress until the cease and desist comes. Keep up the good work.
