Glad to see you're happy with the reception of the game!
Reading this, just in case (you realise it, but one more time won't harm), a word of warning for you: making games with more gameplay are really difficult and time consuming. Right now, you games have quite simple gameplay (which is not a bad thing). It will take much more time and effort, so please be careful with that.
As an example, the already closed japanese game dev studio SofthouseChara put a lot of effort in their gameplay. Often, the adult content was rather scarce throughout the game time.
