I have bad news for you, there are multiple instances of recycled art in the game as well as several scenes where only the "character skin" changes, but it's basically the same scene for different paths (like Ian and Mike, for example). So more of this in future updates, I'd say it's a pretty good bet.You can save your sarcasm for someone else. Re-using art from previous sex-scenes for future sex-scenes is certainly not the play unless you enjoy looking at the same thing over and over again.
It just means she's working less on new art, recycling old stuff. For me personally, this was the first time I noticed it and I hope this isn't gonna be the new norm as it would make things rather boring. You can't seriously act like looking at the same art for several sex-scenes is fine.
In my opinion, it's a bad thing but also an understandable compromise for a one man/woman game. Ideally, there would be more resources working in the game, some outsourcing for the less creative and more tedious tasks. But IRL it's not always easy finding reliable people you can trust to deliver your vision while also keeping the game profitable. Of course it would be great to get more content and faster updates.
