Yeah, a lot of time compressing the images will give weird patches/colors. Especially on skin/lips/and (for some reason) Molly's Yellow Shirt. They are fine in the full size image, but compressing them fucks with it. I try to go back and edit them when that happens, but sometimes I miss some. Like those Sarah images (which will be fixed in the next release - so thanks for pointing those out).I think the renders have always been pretty good. I noticed a few weird patches on Sarah's skin during the her stripping during truth or dare, but that was about it.
As a side note, having played the rest of the game so far now, I can say that I did notice that as the game went along you did start adding some dialog and descriptive text during the sex scenes, as opposed to the first few that just had a few clicks.
I'm happy you didn't give up on the game! I thought for sure you were done with it. Yeah, I really do try to constantly improve what I'm doing and honestly do appreciate people's constructive criticism. I welcome people telling me I suck, as long as they tell me WHY I suck. Hopefully you can see that improvement as you progressed through the game.
