1) there are two wrong "peeks", one at the beginning, the spot is placed on the reception desk but the image shows the two girls with the tartan miniskirt that you see in the following scene. The second is in the weight room, the spot is placed on the door and you see the lady stretching. In this scene, if you pick the second answer the game stops.
2) No matter what I do, I have no success with the receptionist (but it might be me being stupid). EDIT: Done, but with version 1.2
3) The very first time I played the game, I actually started from day 2 (?!) The receptionist was in her normal clothes and the two girls in the background hated me.
4) With Casey, I cannot go past the first date. Everytime I meet her, it's always the first time. EDIT: I finally understood what to do.
5) Nic invited me to her home, but there is no such place in the map. I mean, there is an indication, but no clickable spot.
