Some quality of life updates that were needed.

So far before this point, the game was rather playable to many people. Despite this claim, there were areas that needed to be improved upon such as being given a hint to backtrack to obtain a key to move on. Another new addition is the presence of the footstep sound effect to let the player know that they are moving and pressing the WASD keys. Lastly, I have added in a toggle-able feature to turn the flashlight on or off using the G key.
