Unfortunately, I will be REJECTING this map submission.
Theme: Although we do have a couple of FNAF-related maps, we don't have any themed after Mangle. Hence why I believe your map to be originally themed. Good job on picking out something new!
Build: Personally, I think the build could use some work. I see what you were going for, it just wasn't executed as well as it could've been. The main issue lies in the overall structure and shaping of Mangle. This is just way too simple, making it barely resemble the actual character.
Parkour: The parkour fit the medium difficulty in both length and difficulty, but it had a couple of issues. The first of these pertaining to the use of barriers. Not only were they not labeled, leading to a lot of confusion, they also made the map quite exploitable. The other issue was the actual composition of the parkour, or more so the lack of variety in the composition. You used a lot of the same jumps throughout your map, be it ladder jumps or straightforward cobble wall jumps. We want much more unique and enjoyable parkour than this, don't be afraid to use a wider array of jumps.
I hope you take these criticisms into consideration when submitting maps in the future, good luck
