Objects half visible
Making the objects half visible makes the game more thrilling, it makes you think. What's the sense to glow the object and make it very obvious that that's the one you need, did you used your brain. This game is more like puzzle/mystery solving. Sneaking than attacking. Focused on the story. We should be thankful that someone has created a game like this for Mac. Use intel and nvidia graphic card for this to look good. I use intel x3100(not a good vid card),but it just looks the way it is. No dropped frames even on full resolution.
This game was originally on windows so I dont think it will look good on PPC.
