Change of concept

Added: 

• Day/night cycle. 
• Temperature system: at night and every day it gets colder.
• Inventory and fire system: to light a fire you need to find branches and a leaflet, then put the branch on the ground and light it with the leaflet. 

The map has been redone, new objects and locations have been added. 

In addition to snowmen, 3 new types of enemy have been added (some mimic the environment). 

To make it easier to find your friend in the storm, there is a Q button that makes a loud whistle. 

Optimization.

In the future it is planned to implement hunger and trade systems.
