Hoi eeq,
Sorry to tell you that your map have been rejected.
The theme is not really bad, it's not the most original thing, but it's still decent. The build is not really good, it's pretty plain and not really attractive, there is also a lot floating jumps, making your map messy, try to build your parkour a maximum on/in a build. The parkour is not really good, it's pretty repetitive, try to use more type of jumps, like ice, soul sand, fence, slimes…
Thanks for submitting your map, would be really good to see more maps from you !
