Thanks for a great game! As an FYI, I was just playing the 4.5 version and in the scene in the MC's room when Frida delivers the invitation, I chose the "friendly" option when she was leaving the room, but when Frida gave feedback to Amelia there was still a flashback to Frida giving oral to the MC. It felt as though either a flag was turned on by mistake, or the code isn't checking for one. This happened at another time (in 4.4, IIRC) but I didn't take note for feedback.
Anyway, I hope there's a lot more plotline to come, and will continue supporting when I can.
