Mobs Gets Faster Every Day Challenge

All mobs gain approximately 40 percent speed per Minecraft day. It stops working around or after day 120, with speeds over 50x. It's a challenge, to beat minecraft while mobs are day by day getting stupid fast. 

Main.js is really just one simple script that adds a speed effect to all entities that have the movement component based on how many days have passed. It also displays on the players screen what day it is and how much the mobs' speeds are amplified.
