Hello Conorbg,
Unfortunately, I will be Rejecting your map.
The theme is original, but the build isn't great. It seems quite flat, and is a bit plain. I would suggest trying to add a bit more shape and depth to the build.
The parkour has great variety, you use a good variety of blocks and items, creating original and enjoyable jumps. However, the parkour is too difficult for a medium, you did use quite a few jumps that do not fit the medium difficulty, especially harder variations of neos, pane towers etc.
The length is good for a medium map, possibly a little short, but not a huge deal, and the difficulty suits a hard map.
Thanks for submitting your map! I hope to see more maps from you in the future.
