Jump was the first custom map I ever made on Minecraft. It is a parkour map with a load of different types of parkour. I know there is an in-browser flash game called Jump, but that didn't yet exist when I began construction on this. Please don't sue me.
I stopped updating it a long time ago, but now I have some new ideas for sections of the course. You can be excited about the following:

• Cactus hopping. Yes, You will probably die.
  
• Christmas-themed section including jumping over reindeer heads.
  
• A piston wall. You will have to time your jumps and, at the same time, be very quick.
