Hi. Thank you for your feedbacks! I'm glad to hear that the choice of theme means something for you too :)
Of course, the actual state of the game doesn't represent the original aspirations. I plan to start creating the characters animations during June, to avoid the funny part of T-Poses everywhere. Ideally, I would like to replace the UI elements by diegetic signs, and I guess adding animations should help a lot to reach this goal.
The easter egg suggestion is awesoem, I will definitly think about it XD
About the mechanics, I agree that it may require some additional work. Except in the first picture (where Anna tags the shop window with the punk slogan), there is nothing. My idea is to add visual and audio feedback every time you try to help a friend, even if it's not with the right item.
I want to keep the gameplay as simple as possible to be able to reach non-gamers persons but the idea of QTE is appealing. Maybe something like « Ok, you can take 2 or 3 spraypaints and use them wherever you want, but each try will consume one object ». So you can't just spam each picture and have to understand each girl's feelings, behaviours and hobbies. And there are funny animated scenes when it's not the right item.
As you can see, there is no shortage of ideas. I have to schedule this now ^^
