Hello Snaukbell, I am sorry to say your map is being rejected.
Theme: The theme is pretty unoriginal, we have lots of giant Minecraft block related maps already.
Build: The build was just 3D pixel art, which we don't accept as the main focus of a map.
Parkour: The parkour was very repetitive and far too easy for even an easy map.
Please read the submission guidelines here:

Thanks for taking the time to submit your map, hopefully, you will submit more in the future!
Have a good day, and happy map building- Cele <3
