All of his games have been the same in that regard, i've no doubt his new game will also suffer the same problem.
Then again it's not exclusive to this dev, it's a too common theme in adult gaming.
A lot of them struggle with endings.
The vast amount of shit endings i've seen at the end of good games first shocked me and now is just too common for me to care.
Unless proven wrong, which doesn't happen often, I just assume a shit ending is going to happen.
It's so common I was genuinely shocked when I got to the end of a certain futa protag game recently and I liked the ending to it.
That said, this dev has managed to put out 3 games, 2 of which were really fucking good, and also 3 shit endings.
