Gameplay as of Week 3

Here is an unedited gameplay video for 'Zombie Mower'.
Gameplay that has been implemented:

• Mower Movement
• Zombie Interaction (Magenta Squares)
• Human Interaction (Cyan Squares)
• Power Ups (Blue Squares).  So far the only 'power up' is money acquisition.
• Obstacle Interaction (Red Squares).  This needs to be a lot more dramatic.
• Zombie Wall Interaction (Purple Wall). Not shown very much during this video.
• Store To Purchase Upgrades. 

Some of the only things left to add are the Title Menu and a Game Over condition.
