Hello Psychlone,
I regret to inform you that your map is being rejected.
The theme is original, well done.
The build, as mentioned above, could use some more details throughout. I also recommend trying to incorporate some of the parkour inside your build.
The parkour is repetitive throughout, so make sure you use different types of jumps throughout your entire map (rather than stone.) The majority of your parkour is also floating, which makes your map messy and takes away from your build. The difficulty of your map is also inconsistent, overall feeling a bit easy for an insane.
Thank you for submitting this map, I would love to see more submissions from you!
