Hi there Donkasem!
Unfortunately your map is being REJECTED.
The theme is unoriginal, as we already have Rubik's cube maps.
The build is accurate so good job on that, but is or less 3D pixel art. We do not allow 3D Pixel art. Ensure that you make a main build/island which you can add details and depth this build is currently missing.
The parkour itself is too difficult for an insane and the jumps are very repetitive. I would recommend using a variety of blocks such as glass panes, cocoa beans, heads, piston heads/bases, soul sand, ice, water, etc, so the parkour has some variation.
Thank you for your submission. Have a good day/night
