Hello Kontarix,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is good. The main part of the build is accurate and shaped nicely.
The parkour is very repetitive, especially at the beginning where it is mainly iron bars and ladders. As the map goes on, there is some more variety, but still quite repetitive in areas. I would recommend experimenting with a larger variety of blocks and items when building jumps. This will give your map more originality and will overall be more enjoyable to complete.
There aren't many floating jumps which is good, you implemented the parkour into the build well.
The length is good for a hard, and the difficulty is more suited to a medium, with maybe a couple of hard difficulty jumps.
Thanks for submitting your map! I hope to see more maps from you in the future.
