Hello King_Fuff, I would have to give this a -1. This is for a few reasons:
The build isn't really...a build, it's just a wool box. I know that's what you were going for, but it is pretty boring and boxes are generally unattractive, unfortunately.
Secondly, there are many portions of the map (such as the crawling maze, or crawl space shortcuts) that cannot even be played, as the recommended version for parkour is 1.8.9, so all maps need to be functional in that version. In addition, the parkour isn't varied much, with the majority of the map being normal, ice, and ladder jumps.
I would also
highly recommend changing the theme. A "Padded Prison" is a sensitive topic for many people and brings up an ugly history of when those with mental health problems were not treated in a humane way. While this map doesn't look much like one, I would recommend changing the theme away from that, and not trying to make the build to look more like one,
please, do not try to make a realistic padded prison i know this is in small font but i really am emphasizing not to
Aside from these critiques, the sections of the map I could access did fit the difficulty, so that's good, although varying the jumps and mixing them around would be much better altogether.

good luck on your submission!
