There are only a few slight details in your game from my subjective point of view:
The sound of the messages after a while is already annoying and it is more annoying that it does not have a direct option to disable it (it took me about 20 minutes to remove it without removing the rest). 😮💨
The version I played still doesn't have H, haha 😭, but I saw that it's finally being introduced. I'll play it again until the step-mom and step-sis have H (hopefully when they do it won't be easy to get).
The messages for certain actions such as up affection are the same and the game becomes a bit repetitive. In my humble opinion 2 or 3 different messages for each character would make your game much better.
I swear and promise you if in a future update, where the stepmother and stepsister already have H and if is unique and difficult to obtain, I will make you a very reasonable donation for your effort and to keep you motivated. 😊💪
