This is because it's not a 3D game that it take time (and that every character is not the same that any other game). He stream every week between 4 and 6 time, i don't know other creator that do the same. And you can count that he work for the game between 35 and 40 hours/week and have work as director of "my Kompas" company too.
I prefer few great update than a lot of crappy. Every update is for multiple hour of story (if you don't skip the dialogue, a big part of this kind of game).
For the 60K$ month, a lot of it going for his team and for the thing he is unable to do (like to pay an other company for the animations,). At the end, he have a good salary, but not as big as a lot can imagine.
Any patreon can follow the develloment track and have some bonus depending of their participation (vote, Wallpaper, etc...). I am a patreon but i am not forced to be, because the game is free and available for every adult who want it (except country restriction).
The game progress smoothly and sometime we have surprise update (like two month ago, with consuela), so please, don't complain.
