Hello unjolly,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is good. It's well built and accurate to what you were going for.
The parkour is quite repetitive. You did create some original jumps which is good, but there are a lot of grouped sections of jumps. What I mean by this, is you would have a sequence of just ladders, then just ice blocks, then trapdoors etc. Try to mix up your jumps a bit more, as well as experimenting with a larger variety of blocks and items, to create original and enjoyable jumps.
The length suits a long easy/short medium map, and the difficulty suits an easy with some medium jumps.
Thanks for submitting your map! I hope to see more maps from you in the future.
