Hi there Asd__,
Im sorry to tell ya your map has been rejected.
The THEME is a bit unoriginal, there are quite a few maps that look like this such as bookshelves.
The BUILD is lacking in detail and doesn't have a main build. Please try to make one main build that has parkour around so it eliminates all the floating parkour (Which isn't accepted anymore) !
The PARKOUR is quite repetitive and lacking in varation. It does fit the length of a medium, but it's a little too easy and could use more variation such as chests, slime, water, etc !
Thank you for the submission, I hope to see more from you. Have a wonderful day !
