Update 0.1.3

Nothing too crazy with this update! I feel that I've gotten a lot of the core gameplay and mechanics down now and will start making more guns, enemies, level types and more of that sort of stuff soon. I'm having a good time with this project and if you're reading this, I hope you are too!

0.1.3 Updates: 

1. Fixed save/load issues
2. More guns:
3. Freeze Gun
4. Pistol
5. Dual Pistols
6. Enemy Tracker Gun
7.  Upgrade rifle damage
