Hoi Kaaspannenkoek,
Sorry to tell you that your map have been rejected.
The theme is not that original, even if there is no "Dungeon" maps, there is still some maps with a similar theme (ForestTemple for example), the build is not really good, I found the dungeon itself pretty good, but the problem is all your parkour is floating around the build, making your map messy and unattractive, please try building your parkour on/in the build. The parkour is not really good too, it's quite repetitive in my opinion (For exaple, most of your map is normal jumps, and at the end, there is only cobble wall jumps.), try using ice, soul sand, iron bars, water..
Thanks for submitting your map, would be really good to see more maps from you !
