Fix the server

Concept game for SKG community game jam  

(Win version hasn't been tested)  

This game will become an exploration and crafting game where you try to find resources to survive in a game whose server is shutting down due to rare fog covering the world caused by some virus the devs can't track down.  

You're time is limited as the devs have set up the date to shut down the server, the clock is ticking down. 
If you manage to get rid of the virus you'll have a way to run your own server and keep playing the game for as long as you want.  

The virus corrodes you. If the level gets too high you won't be able to help the server anymore. Find medicine to get the level down, and find ways to install purifiers in the overworld to create safe patches where the fog is dispelled.
