Pros:

really long map - it took me about an hour to play
much attention to detail

Cons:

somewhat too difficult - I tried it 5 times and never made it on the train

Conclusion:

I do know Linz and therefor the map was great fun to play. I recognised like every spot on your map and sometimes just thought "hey, i was at that plce like an hour ago" that's really great
btw - you set the ursulinenhof on fire, heavy hint, it has been what, 2 years ago when it burnt nearly down?
the train station is well down, just looks like the real one. 
And you took the real announcement which they use on the station, did you?

all in all - thanks for the map, its great!
