Hello Bikleplays,
I'm sorry to tell you this map is being rejected. The theme is not original, as there is already a slime themed map already on ManaCube. Please check the Parkour List before you start building to make sure your theme is original! There isn't really much of a build to judge, as the map is mostly just floating slime and brick jumps. In the future, try to have a main structure with the parkour on, around, attached to, or inside of it.
The parkour is not mixed or varied much, with most of the jumps being of normal and slime blocks. In the future, try to use many different kinds of blocks all throughout your map to make a unique and interesting course. The parkour was pretty long for a medium map. Please use the Map Submissions format in the future to make sure we have all the necessary information to judge your map! I would also recommend looking at the Mapmaking Wiki guides, as well as /warp beta on the server or the Accepted Maps subforum to get a better visual of our current standards.
Thank you for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
