Hello Conorbg,
Unfortunately, I will be
Rejecting your map.
The theme is original, but the build isn't great. The chef looks quite flat and blocky. I would recommend trying to add a bit more shape and definition into the build, to make it more attractive.
The parkour is good. You used a large variety of blocks and items, creating original and enjoyable jumps, so well done! The parkour is also implemented well into the build.
The difficulty is good for a medium map, but the length is far too short for a hard, and a bit too short for a medium map. Please read over this thread -
https://manacube.com/threads/must-read-map-submission-information-format.649/ to make sure your map fits within the requirements.
Thanks for submitting your map! I hope to see more maps from you in the future.
