Can't post a review yet so i'll post it here. If someone wants to copy-paste it to the review section, feel free to do so.
This is the steam demo, so expect 0 18+ content.
Played the whole thing and it is bare bones and broken atm.
After getting 90 affection (and 170 my case because i wanted to test the socialise mechanics) with the first girl, nothing happens. The first female teacher that gives you a quest? quest is broken, you can fish but it does not register for the quest.
Gaining 'stats', the charm and knowledge stat (first and second floor of the school) has 0 impact as of yet. No abilities or anything gained in the 0.2.21 version.
Working in the coffee shop is also broken. A full shift should take the entire day, but it just consumes the current portion of the day. Chisel from the fisherman gives a single (guess AI) 'image' of a girl studying. Nothing interesting there.
Though i must say, i see potential in this game. the inventory mechanic looks interesting and it looks like every time you 'win' a social battle, the opponents stats raise. That could make for an interesting juggle to battle the teachers and side characters to gain stars/items and complete sets & combo's in order to progress with the main characters after there stats have gone to high.
Though, lucky teacher was a bit of a slog on the gameplay side so i'll patiently wait where this one goes to.
