Hello tom_g232I am sorry to say your map is being rejected.
Theme: This theme is unoriginal as we already have maps based around dungeons.
Build: There's no main build, and the build that there is is not incorporated into the parkour. We would want to see a more main build that has parkour around it.
Parkour: The parkour is mainly floating and does not have any variety to the blocks.
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
