No shortcuts, no. I have played the games a lot, so I know by know how to move around in the scenes, but some are harder than others that is true. I didn't find this game harder than any other though personally, but we're all different. The only tip is to make a mental note of what is near the exit or something like that. When you say museum, I guess you mean the Norrkoping Museum? It can be tricky but I usually memorize something just before the exit or to the left or whatever. The brain can remember thing more easily if you associate it with something else. It works very well, so try that.
