I regret to inform you that your map is being rejected.
The theme is unoriginal, as we already have several maps relating to the nether (DeathMountain, TheNether, NetherCastle.) Before creating a map, please make sure that the theme has not already been done before by going here: https://manacube.com/threads/parkour-list-with-theme.20194/ The build is quite scattered, and it appears quite messy, so please try either having one close structure or having the structures be close together. There could also be some more details incorporated into this.
The parkour has a bit of variety throughout, but try using some different types of jumps (vines, heads, glass, iron bars, etc.) The parkour also gets quite confusing at points, so please try to have plenty of indicators so players know where to go. The length of the map is more suited for the medium difficulty, but the difficulty of the jumps is good for the difficulty.
Thank you for submitting this map, I would love to see more submissions from you! Have a nice day,
Kristina
