Map Info:
On the Run is an infinite parkour map (If you never die), the parkour will change if you restart the game so you are not running the same parkour over and over again. You have to run and parkour really fast, you don't have the time to stop, because Herobrine is flying behind you. The game ends when Herobrine Catches you or when you fall of the parkour.
While you're running you can collect Emeralds to increase your Score. Your Score = Time * 10 + Emeralds * 2. So when you've runned 30 seconds and collected 5 Emeralds, your score will be 310. In the Spawn are signs that show you your latest and best scores.
There are also parkour parts where you'll get a snowball, you have to trhow it on packed ice to get through it. When you get in the Library, you've to look what color the wool block above the iron door is. If the wool block is red, you will have to walk over the pressure plate which is placed on a red wool block to open the door.
