Hello KingOfMonkeys,
I am sorry to tell you that your map has been rejected. The theme of your map is unoriginal, since there are multiple maps on Manacube based off of rainbows already. Try to have an original theme that you base the build off of in the future! The build of your map looks like a rainbow, but it could have better shaping. Right now it looks a little blocky, less smooth than rainbows usually look like!
The parkour of your map was very repetitive, with mostly only regular jumps and ladder jumps. Try to have Parkour variation in your map by using different blocks like chests, water, glass panes etc, to make it more fun to play. Most of the Parkour was also floating. Try to avoid floating parkour, and having it attached to a main build! The parkour of your map had good length for a Medium map, but most of the Parkour felt Easy in difficulty. (GamersDecision)
Thank you for submitting this map! If you have any questions, feel free to message me on Discord.
