Assuming you all got the Walkthough, I can tell you from my own experience it is hard to follow.
The time you have to be at locations and sometimes only on certain days make a lot of things seem buggy that sort of are not buggy (
Except for you needing to be able to read the makers mind and know exactly what they intended for you to do.)
There were some things I ran into that if done before another thing could bugger something.
Note >>> I am not saying it is not and aggravating repetitive piece of procrastination, and wasted time.
But after you grasp what to do, when to do it, and the order in which to do it... LOL, It can be beaten, and it is in a lot of place's very fun, and entertaining.
That walk-through is your key, and googling problems on this thread is also your friend.
Good Luck!
These were a couple that blew my mind and the answers I got searching this thread.
