Hey Tightly, I have played around with this app for a while, like since Breast Expansion or earlier, played both PC and Android. I really liked what it has going on, and I'm hoping to see what can be added in the future.
I sometimes see info about at the end of a thread we can go to Mia's room to do stuff but it just says the door is locked.
I am really curious about the buildings and beach areas, and I want to see them get a lot of activities, same for home, like bath or shower scenes or interactions.
I want more cool stuff in the shop. TP was the currency right? The Vampire plushie was fun, so any more of those would be cool, maybe a Rabbit plushie for a Bunny Girl for spring time. Hopefully more minigames too.
Also, kinda strange to say I'm sure, but could you also make a Normal Route for Mia? My idea is we are exploring all of these options but we haven't even tried to just go with the flow without modifications, so why not simply put a tracker in the paths section of the game telling us we can just ask her out like a normal couple, maybe a joke where Tightly is our wingman or something, or this Route is not shown at all, a secret route, and we have to figure it out, maybe the coffee shop receipt could give tips or guidance.
Anyways, these are things I think of when playing your game. Please be safe, thank your for this game, and good luck going forward in this games development.
Oh and please consider all of what I brought up in this comment, the normal route felt clever and funny, and it was nagging me when I last played.
