Unfortunately, I will be REJECTING this map submission.
Theme: As I already told you before, this map is most definitely originally themed.
Build: The build has not improved since the last submission. For starters, I don't get the cobblestone ceiling. Sure, it's supposed to look like Mangle is clinging on to it but it's just a giant square. A giant bland offputting square. Regarding Mangle itself, it's still not in good shape. If it didn't have a head your map would just look like a bunch of blocks with little to no meaning. The build just doesn't look like Mangle, you're taking an improper approach. Focus on giving him some shape and adding details that really cement the fact that it's Mangle.
Parkour: The parkour fit the hard difficulty in length and difficulty, although it's on the easier side of things. The major issue with the parkour, just like last time, is how repetitive it is. The parkour is so straightforward that it gets boring a quarter of the way in. You re-use a lot of the same jumps and blocks for it. You'd just make the player to the same 2b/3b block-to-block jumps and add some vines or ladders here and there. It just wasn't fun. Try to be more creative!
I hope you take these criticisms into consideration when submitting maps in the future, good luck
