Hello Mutant_Cacti,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are a few maps already relating to colours (
RedvsBlue - Medium, BluevsOrange - Hard for some examples) Please refer to the document linked in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
There isn't really a main build. In the future, try to have one or two main builds that are relevant to your theme, and then incorporate the jumps into that, rather than just having jumps over the void.
The parkour is very repetitive, as most of it is normal blocks, with some cobble walls at the end. 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 overall more enjoyable to complete.
The length is good for a medium and the difficulty is good for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
