Thanks for the bug reports! The lag spikes are due to the concentrated pixel-image suddenly loading due to the minigame. Was planning to change the high resolution scenes sooner or later, but since you mentioned that, maybe I'll redraw them while adding the other intercourse minigames (thus, removing most of the CG bugs mentioned). I'll also try to fix the other bugs you mentioned, but system limitations that need quite a long time to alter(such as the inventory) might stay a little longer since I tend to update my game once a week.
The lag spike isn’t so much the issue, the issue is that I think it’s frame rate based, and the lag spike throws off the timming for the whole event. It causes the window for when to click to be when it hasn’t flash yet. Which I can still sometimes perfect but it’s a lot harder without being able to rely on the visual indicator.
