Multi Challenge

It is a series of different well known stages consisting of a dropper, a maze, parkour,a find the button and a try to die. It is for 1.12.2. I am sorry if it is bad but would you please comment on things to fix as it is my first map. That would be much appreciated. By the way I was 12 when I made this. I made it by myself and without world edit. P.S. I am sorry about the blown up village. The villagers annoyed me also if you are a youtuber recording this then please leave a link of the video in the comments so I can watch it.
