Hello!
Unfortunately your map is being REJECTED.
The theme is original, so good job on that!
Unfortunately, due to the nature of the build, it is hard to get some depth and texturing which your build is currently lacking. There is also some overall shaping lacking.
The parkour itself is sadly inconsistent. Where one checkpoint will be a lot easier and not suited to an insane map in comparison to another. There is some variation; however, the parkour does still feel repetitive as it's in clumps. You can add more variation with blocks such as panes, water, minecarts, cocoa beans, piston heads/bases, trapdoors, etc.
We hope to see more maps from you in the future!
Have a good day/night
