Thank you for the feedback! In order:
-True, the only real change I plan to make to the wine is making it limited use, but that will be after there is enough content that it doesn't feel like a grind to get lewdness up.
-You've been just getting good rng, each scene gives 10-100 pregnancy build up, so at least one person is going to have to go 5-6 times to get pregnant. I didn't want it to be too rigid (set number = feels forced). I might make the top number lower if the frequency is too high (I just like the idea of getting a rare instant pregnancy). Not sure about the graphics flicker though, I am using the same method (waiting 15 frames between each image) that I use for the groping and kissing animations. Maybe having the initial image stay on screen until the player presses z/enter will have it seem less flickery? Maybe having the middle two images loop a bit to simulate the egg not coming out all at once but needing some pushing? I will play with these ideas and see how I like them.
-The two-frame animation is me toe dipping in animation in general, I haven't ever even attempted it before. More frames could be added as I become more comfortable with the process, though whether that happens this game or a future one IDK. I was going off how Breast Mafia puts animation in their games, though they do it MUCH better than I do currently.
It is good to hear the graphics were put in right, one thing I tried with this update was moving from my usual brush in krita to a more flexible one. This allowed me to more comfortably use a bigger canvas size to draw, though I was hoping doing so would allow me to use a bigger size for said brush which would keep the CG looking good when I resize them to RPGMaker's image size. Didn't get the result I wanted, but it was a step in the right direction.
