Since I've been a parkour master, i've decided to make a parkour map! this is my first map so maybe it is buggy. But i think if you use 1.8.x it should be fine. The reason why i need you to use 1.8.x versions is because of that the /title commands doesn't work correctly in 1.9 or above. The name of the map is Fatal Parkour, basically when you wear the required helmet, if you fail the parkour you'll die. I used a lot of redstone so if you think there is a bug tell me. And also I forgot to switch off Creative mode when posting. Please switch back to survival mode. Download link for map down below:
