mildly entertaining match 3 game. but what a grind, my advice dont make everything unlock with the same currency. you unlock: permanent upgrades, consumable upgrades, dates with other girls, additional dates, additional scenes (some are the replays of the gameplay scenes, which you grind to get more currency).
recommendation, make the first date will all the girls available from the start, you dont have a story nothing connects just unlock it and additional dates for the same girls should be unlocked for "completely" a date, upgrades and extra scenes are fine.
