Thanks for playing and thanks for your great feedback. I'm glad the compass helped you find your way, it's easy to get lost without it.
Oh yes Chapter 2 can get messy in a hurry if you don't quickly dispatch them.
If you proceed to the top of the map in Chapter 3 (either outside the building on the West side, or through the building on the North side) you will see a larger battle taking place, but you're not meant to fight in that one so be careful you don't get killed quickly when approaching.
Cheers
