Hello silvermisst,
Unfortunately, I will be Rejecting your map.
There theme is original, as there aren't any maps like it, but it is a bit hard to tell what it's meant to be. In the future, try to have a larger build that replicates your theme.
The parkour is very repetitive, as it is mainly normal blocks and ladders. Try to experiment with a larger variety of blocks and items when building parkour, as well as the way you utilize these, as this will make your map more fun to complete.
Most of the parkour is floating. Having an excessive number of jumps floating around the build & void can make your map look a bit messy, so try to incorporate the jumps into your build where possible.
The length and difficulty are good for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
