Hello Frazz,
I regret to inform you that your map is being rejected.
While your theme is original, I recommend using a theme where you can have a more detailed build and allow your parkour to have more unique jump styles, which is seen in modern Manacube maps.
The build is a bit bland. As mentioned above, try having a theme where you can add more details and overall make the map unique. I would also recommend expanding your map a bit.
The parkour has some different jump styles throughout, but feels somewhat repetitive at times. I would consider the difficulty of this map inconsistent, as there are some jumps that are definitely too hard for an expert map (even with easily grabbable checkpoints.)
Thank you for submitting this map, I would love to see more submissions from you!
