i tried several times - nothing to click on.
But after several days, i tried it again - and it worked suddenly.
I can't repeat myself enough:
this game is a boring and annoying piece of crap. It could be a top game though. I like the models, i like the setup, i like the story... but that sandbox-grinding and lookout where to continue just sucks.
A sandbox game should be used to open all paths, and let the player decide where to continue what path.
But this is not like that. Over here the sandbox is used to put straight stuff behind puzzle-grind (like firealarm, or spy on someone EXACTLY at a certain time, or try to steal some evidence EXACTLY at a certain day, at a certain time).
BULLSHIT! - sorry - i really can call such stuff as bullshit! If i would want to play such stuff, i rather play "hidden object" games or the whole "myst" series.
