Hello microgear,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is good. It is accurate to what you are going for, and overall well built, so well done!
However, the parkour isn't great. A lot of it is repetitive, you mainly used ladders & fences, as well as a lot of neos. The difficulty also varies a lot throughout the map, some sections that are more suited to a medium/hard with some jumps suited to expert/insane.
I would recommend experimenting with a larger variety of blocks and items when building jumps, it will make your map more enjoyable to complete. Also, try to cut down on the number of neos, as this makes it quite repetitive, and difficult.
The length is good for an insane, and the difficulty is suited more to an expert.
Thanks for submitting your map! I hope to see more maps from you in the future.
