Team 3 Sprint 3

Changes: 

-altered bullet color and size to make more visible 

-lightened tile map 

New additions: 

-crates for power ups that player just needs to touch to collect 

-player can see number of power ups collected in the top left corner and can use them by pressing space bar 

-additional level with new tile map and "new level" button 

-Level 1 would likely be "tutorial level" 

Bugs: 

-power up should increase speed of player sprite but not working -trouble implementing countdown timer for power up 

-need to hide new level button until end of a level -still need to get zombies to move around obstacles
