Mr. Snuff

Make me happy, I finally finished (and drew and drew) my first ending! The ending is good because somehow M/C (I think that's how it's written) survives and kills the maniac. I just need to finish it properly, like draw a couple of new scenes and that's it, so wish me good luck.

Anyone who sees this post, please give me some advice on creating the novella. I'm a new game developer, and I've never developed anything in the game industry before, not even a single game, so I decided to create a novella similar to BDT (Boyfriend to Death). Like BDT, there will also be three villains (if I named them correctly), and half the code, as well as the scenes, art, and characters, will be drawn and written (I might attach screenshots). Of course, I haven't finished the first plot line yet, but I'd like to hear advice from those who know their stuff. I'd like to know how to best create endings, whether I should have written the script in advance, and how to compose the music if I don't have any tedious elements.
