Hello,
Unfortunately I will be
REJECTING this map submission. Here is my input:
Theme: I was going to comment on there being a cathedral map already but you have since changed the name, so it's original.
Build: The build is really nice - well detailed with good block variety and nothing in particular stands out as ugly or misplaced, so great job there.
Parkour: The parkour was the problem with this map - the difficulty varied a lot between jumps with some being easy and some being pretty hard. I found two jumps that I believe are impossible in 1.8.9 (maybe I'm just terrible but I couldn't make
this jump or
this jump after a lot of attempts). I would keep buffing your parkour to make almost all the jumps the same difficulty. There were a few 4 +0.5 block jumps, so maybe less of those and more of other types of jumps that are equally hard. There were also a lot of checkpoints on your map with negated some of the difficulty by having more respawn points than the typical insane.
I'd love to see more submissions from you in the future, and have a great day!
