I regret to inform you that your map is being rejected.
The theme of your map is unoriginal as we already have many maps based around a waterfall (WaterfallMadness, WaterFallTemple). Before creating a parkour please make sure to check out this template here (https://manacube.com/threads/parkour-list-with-theme.20194/) to see all the maps accepted on the server!
The build of your parkour is also a problem. The build is mainly just a wall with water and floating parkour, which is no longer accepted on ManaCube. Next time try considering making one main build with lots of detail around the build.
The parkour of your build fits the length for an easy map so good job on that. The difficulty is mostly good but some jumps would fit better in an medium map. You can skip a majority of the parkour by swimming up the waterfall, try using /barrier to patch it up. With that said, the parkour is lacking variety, all that is there are regular jumps, ladders and chests. Try adding more jumps with unique blocks like chests, water, glass panes, brewing stands, etc.[Elly]
Thank you for submitting this map, I would love to see more submissions from you! Have a nice day,
