This build was made for map testing, to progress through the different maps just touch the green cubes:

What I've done on the game:

--> Flashlight now uses batteries;

--> Items, the gun and doors, now have sound effects;

--> Enemy's range is now longer;

--> Code Optimization [Runs better on weaker hardware];

--> Underground Map now got ambient lighting for open spaces;

--> Underground Map got some new areas, non existing ground collisions;

--> General Mesh Optimization on all maps;
