Hey all! couple fixes thanks to some of you finding bugs! 

- fixed the flashlight state not saving between levels.

- fixed some collision issues in the kitchen that would prevent the player from shooting freely. 

- fixed the kitchen zombie respawning after being killed.

- fixed a rare case where the player would get stuck in place after killing an enemy from too close.

- added a invisible wall to prevent the player from climbing back to the road after the crash.

Known bugs that are not fixed yet:
