Hello Nico8k,
Unfortunately, I will be Rejecting your map.
The theme is original, as there are no maps based on head hitters.
The build isn't great, as it's mainly just a box with the parkour inside. In the future, I would recommend having a build that is relevant to your theme, and then incorporate your parkour into that.
The parkour is very repetitive, as all of the jumps are head hitters, I do understand that is your theme though. In the future, try experimenting with a larger variety of blocks and items when building maps, as this will make your map overall more enjoyable to complete.
The length is good for an easy map, and the difficulty is good for an easy/medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
