Glitch Runner is a small but challenging Minecraft mod that adds a "virus" to your Minecraft world.
This virus will slowly corrupt your Minecraft world. As the virus spreads it will slowly increase in speed.
The virus must be avoided at all times because touching it will result in your death.
You must constantly be running from the virus because if you stay in an area for too long you may find yourself trapped with the virus all around you. And yes, the virus is in all three dimensions, so nowhere is safe.
There is also a glitch entity that can spread the virus and will try to kill you. Oh, and it can also clone itself, and teleport you.... The entity also spawns in every dimension. There is no way to stop the virus. The only thing that you can do is - RUN!
If you want to make the virus spread faster or slower, you can type in this command "/gamerule randomTickSpeed (number)". The higher the value of number the faster the virus will spread (20 is default).
