Hi, thanks for sharing your thoughts. I think it's comparable to the length of a single anime episode or manga chapter that usually contains one action scene and the setup that leads towards that action scene. If you hold that kind of skip button on an anime episode then yeah, it should be done in a few seconds instead of the usual ~21 minutes per episode of an anime.
Please note that I'm also working full time and this is a hobby of mine that I do for fun.
The Chapter 1 had 252 unique renders and the file for this chapter contained 1160 lines of code (around 560 lines of dialog). I think it's important for me to be super duper transparent since now I have a Patreon and I hope that helps manage your expectation before subscribing.
