Been playing this to completion a few times the last few days. Might be my favorite H-game on Itch.io!
I play on Android S23 and my 1st playthrough i was able to talk to Grace at the vault. However it bugged out and her room went away before I could get her suit. Now I have done my 3rd runthrough and have never been able to get her room to spawn. Of course the other 2 options for her fate would ruin that, but I tried them anyway.
Hope to see more and more progress soon and beyond! Thank you for this great title with some good quality to it!
