First off this game is huge. I'm impressed. Most of your code looks to be pretty solid, and your tests are clearly advanced for this stage (we cover testing more extensively later on in the course). 

I'm going to concentrate on the area that I see the biggest opportunity for improvement. That is going to be in your modules. First thing I noticed was that you are using `@@global` variables. These are generally frowned on because they can have unexpected side effects. More than that though your structure ends up repeating itself a lot. Many of the methods end up with just one line of difference:

```ruby
        break if new_location[0] < Neighborhood.top_left_limit[0]

        break if new_location[0] > Neighborhood.bottom_right_limit[0]
```
