Hello niqhtless,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is good. It accurately shows what you were going for.
The parkour has some variety, but you did group a lot of the jumps. What I mean by this, is you would have a sequence of just soul sand jumps, then just normal blocks etc. Having repetitive sequences of jumps can make your map seem a bit boring, so try to mix up your jumps where possible, to make more original and enjoyable parkour.
The length and difficulty are good for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
