Hello Bikleplays,
I am sorry to tell you this map is being rejected. the theme is not original, as there is already a slime map on ManaCube. Please check the Parkour List before you start building to make sure you have an original theme. The build isn't great, as there isn't really much of a build at all. In the future, make a main structure with the parkour placed on, around, or inside of it.
The parkour is slightly varied, but not mixed well at all. The map gets extremely repetitive and the map can be broken down into sections by block type, most of the blocks being normal jumps. Try to use many different kinds of blocks all throughout your map to make a unique and interesting course. The parkour is also entirely floating, because there is no build. I would recommend looking at /warp beta on the server or the Accepted Maps subforum to get a better visual of our current mapmaking standards.
Thanks for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
