Is there any instructions for this game? I personally don't know the mechanics of the game makes it more confusing. I don't know what I'm looking for, I just press the mouse keys and I don't even know what I'm going to do next.

This game needs more instructions or something...It may be that is just doesn't work well with my macbook but I figured out that if you click on the top of the hatch it opens and than you enter a new room in which you can't open the door so you find the key which unlocks the fire extinguisher which does nothing. I got stuck. The game seems to stall when you find something and it zooms in I had to restart this game a few times to get out of the screen with the keys... :(

I think it would be a great game if there was better controls to get in and out of rooms or scenes so you don't get stuck. maybe some hints would be helpful. but better directions on how to interact and navigate the game would be awesome. of course this is the 4th in a series and I haven't played the others so...
