The majority of the events are triggered by talking to the characters in the game. If nothing is happening, try going back and talking to everyone again. If there is an action cursor but no conversation is available, try clicking an inventory item on that person. Being able to pick up items in the game is also triggered by conversation with the right person at the right time. So if no action seems possible on a particular spot now, it may be possible later. Turn up the volume. There is no option for subtitles and voices can be difficult to understand. Many of the scenes are very dark. Turn up the brightness on your monitor and/or play the game in a semi-dark room.
