Hello Fraterulus, PepeMario and Flo_49,
I am sorry to tell you this map is being rejected. The theme is not original, as we have many many biome and dimension maps already on ManaCube. There isn't really a main build, just many floating islands of dimension elements. In the future, try to make one main build or structure with the parkour on, around, or inside of it.
Because of the build, most of the parkour is floating, which makes the build look messy. It is somewhat varied, but not mixed well at all. I would recommend reading the wiki guides on mapmaking. The parkour doesn't really fit a hard map, but has sections that are too difficult to be a medium map. It is best to have a set difficulty in mind when building a map! You can look at /warp beta on the server or the Accepted Maps subforum to look at examples of our requirements executed.
Thanks for submitting this map! If you have questions, feel free to message me on Discord.
