Hoi (again) ILeftTheGame_,
Sorry to tell you that your map have been rejected.
The theme is not original, because there is already a lot of "Floating islands" maps like you did. The build could be better, the islands are pretty simple, but the main problem is it's pretty messy, because all your builds are scattered and not only one main build. The parkour could be better, it's a bit varied, but feel pretty repetitive. An other problem is the difficulty. Even if the amount of jump is low, your map still fit expert because your map feel long, but I think your map is too hard for even for an expert, but way too short for an insane. I also think some part are a bit confusing, try to add more signs, or make your parkour more clear in another way.
Thansk for submitting your map, would be really good to see more maps from you !
