Love the game! This, The Headmaster, and Lucky Paradox are leagues above the other games in the genre I've played (which is saying more than I want to admit :p ).
The only thing I want out of the game is for it to be less linear. Systems that let me build relationships with the characters at my own pace would be hugely appreciated. I know that's a big ask and would mean restructuring things greatly if it tied to the main story, since so many of the events assume progress with all the characters.
Maybe the less linear aspects could be to unlock extras with each character once core relationship status has been achieved? For example, once you have a relationship with Sandra, you have the option to learn to cook for her or something and it wouldn't tie to any progress in the main story, but would unlock a bonus scene. Or you could save up money and buy something for Becca (for the thought, not that she couldn't afford it). Maybe you could work out enough to lift Lucy and Alice on your biceps like an old beach bodybuilder, idk :)
If none of that ever happens, I still love the game! Just thought I'd throw it out there.
