Thank you for your response.
I have taken account of everything. Although there are some features that I wont be able to add in the update as cum layer and damaged cloths. There are nearly 170+ frames for each skins(850+ frames), so that will be a lot of work.
There was going to be a masturbation ability in the game but I cut it off because I thought players will exploit this ability if this restores health. If I don't give it that function then that it would served no purpose so I cut if off entirely. Will add this function later after v.0.2 as a small update.
For sister's dialogue I'm glad you are ready to help with it. It would be great if you write some dialogues too after you have made her experience the same pleasure as player.
