Gonna repost my "Tips" cause I'm too lazy to go all over it again xD but please, READ the full comment, 90% of questions related to the game's progression can be solved by following the 4 points I specified just below, other 10% is either bug/glitch talk and/or "When's the next update?" stuff
"Quick pointers to avoid too many back and forths:
1) Make sure the MC (your character) and the girl you want to get the scenes of need to be at 70 points each. For a quick way to do so, whenever the character wakes up, don't get out of bed and pick the option "Spend the day with" and pick the girl you want to "level", each time you get +5 points with a limit of 70 (35 for Mia).
2) The game is based on progression, so even if you have everyone at max "level", you won't unlock all the scenes to do in the same day, you'll need to redo them on subsequent days to see them fully.
3) As for the State Events, you need to do all the scenes of the girl you want to unlock the State of at least TWICE.
4) For any other questions, check the guide in page 1 (below the "Downloads" area) and it will give you a full overview of the game and
a list of the scenes unlockable for all of the girls."
If any other thing comes up feel free to ask away but as I mentioned, please read the whole thing and check the guide cause most issues with progression can indeed be solved by following these points.
