Hey Coubs, to answer your question, yes, everything is programmed from scratch. It takes a lonnnnngggg time to program everything as I am a one-man team. My best tip to start would be to download unity and follow tutorials on youtube. Also, it doesn't hurt to follow some courses online. Hope this helped you!
I am currently changing the way my game is played, there will be more randomly generated levels and some pre-generated ones, kind of like diablo where you have boss levels that are static but the levels in-between are randomly generated.
