I think marleybone should have sidewalks. All I need to do is defeat one boss in marleybone but I can't reach him from all the stupid battles I get in. I haven't even seen where I am supposed to beat him. so if you think marleybone should have side walks please reply to this.
It is the opposite of the other worlds. stick to the middle of the road and you can also pause on most of the iron grates between buildings. Remember this is a kids game and we don't play in the street because it is dangerous and if you are on the roof, stay away from the edge.
As insane as some of that advice sounds...they are right.
My son made progress in Marleybone long before I did. I just couldn't make myself run down the middle of the rooftop. But it works. You will get the hang of it.
Another caution. As you are getting to your destination or just starting out, watch the monsters carefully...they all have a pattern of movement. In a dead end situation (and sometimes just randomly) they will have to make a u-turn, typically in the middle of the path, so in that case you follow the last one to get to that last rooftop.
