Hello Sixx_Often,
Unfortunately, I will be
Rejecting your map.
The theme is original, but the build isn't very good. It is quite simple, as it's mainly a box with pixel art.
The parkour is very repetitive. Most of it is normal blocks, with some ladders. I would recommend experimenting with a larger variety of blocks and items when building jumps, having more varied and original jumps will make your map overall more enjoyable to complete.
You also grouped jumps a lot. What I mean by this, is you had a sequence of just normal blocks, then ladders etc. When jumps are grouped like this, it makes the map very repetitive and boring, so try to mix up your jumps a bit more and avoid grouping where possible.
The difficulty is good for an easy map, but the map is too long. Please read over this thread
https://manacube.com/threads/must-read-map-submission-information-format.649/ to familiarise yourself and 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.
