they surely can, doing things well and fair will talk well for you as dev even after the "project finishes", and you can make a possible continuation or an alternate story around near the same "timeline" and with your knowledge you got from the last project you can again still get support from you fanbase and they already have faith in you because you fairly provided.Like clockwork. The adult VN space (and others) is a game of getting their Patreon/SS going to then milk it.
This dev almost finished his cash cow so he found a reason to slow it down. Same for 95% of the others.
As I wrote previously, it's like a test of their soul.
"Developer, what will you do when you have unchecked money that comes in no matter how little you work?"
95% answer with "less work". Some even answer "Jack shit".
It's a rare few that keep working hard but, more importantly, every dev that slows their work to milk it is just admitting that they fear or believe that they can't do it again. They do not trust that they can make another work that is as well received as the one they're now milking. That's all it is. Whether this guy, L&P (AWAM), JOHN, etc they're terrified that if they finish the first game they found financial success with they aren't good enough to make another project people will love as much.
The twist is that by believing that and milking their one successful work they guarantee that will be the case. It's a self-fulfilling prophecy for them.
but sadly seems like there's barely any logical thinking from some of these devs and want to be like Ubislop
