Hello Crihyde,
Unfortunately, I will be
Rejecting your map.
The theme is original, the build isn't great, it looks a little messy as it is mainly floating islands.
The parkour is very repetitive. I understand with the number of jumps there are in this map, it is difficult to avoid the jumps being repetitive, but I feel that there definitely could still be more variety within the number of jumps. I would recommend experimenting with a larger variety of blocks and items when building jumps, it will make your map overall more enjoyable to complete.
Most of the jumps are floating, please try to implement the jumps more within the build, rather having them floating around it and the void, this can make the map look quite messy.
The difficulty is good for a medium/hard map. The length is far too long, please read over this thread
https://manacube.com/threads/must-read-map-submission-information-format.649/ to make sure your map fits within the guidelines.
Thanks for submitting your map! I hope to see more maps from you in the future.
