Honestly, this game feels like a chore to play. The sexual progression is decently written and the sex scenes are nice, but the game feels so janky and unfinished. All progression is extremely linear and basically tied to Christie's plot line. I played through all of Mary's story expecting the game to open up at some point and let me talk to other girls, but all I got was some contextual scenes with Kat. You HAVE to go through Christie's story to meet more girls, and even when you meet them they're just background fodder once they play their part in whatever task you did for Christie. You constantly look at the 'notes' tab expecting to fill up the empty portraits with other girls as you go, but it stays the same from the start. Tasks are tedious and uninteresting, the dialogue is ESL and kinda annoying at times, whole lines of text are not translated. The game is structurally unoptimized and unfinished.
Good sex scenes and Mary's horniness just aren't enough to get over how annoying a lot things are.
