The problem there is with you, not the game. I am on day 20 and have had several scenes with several girls (including a series that gives you a scene every day for a week). And all that without a guide, other than the one the game actually delivers you by itself.With the "guide" and a full day, I managed to complete the first 2~3 days activity in 18 days before the menu stopped opening (Esc key) effectively ending this one for me.
In that time I saw ONE sex scene when they are watching through the window.
About the menu bug, I give you that. Happened to me a couple of times. Easy solution there: save often or turn on auto save. When the menu bugs, just restart the game and load the last save.
You are just a cranky idiot bitching about a decent game...
