Hoi DylanTheYeetBoi,
Sorry to tell you that your map have been rejected.
The theme is interesting, but when we looks at the build, it looks like more a Rainbow themed maps, which is not original, like Kayla said, develop a bit your theme, because it could be original. The build is not good, it's pretty unattractive and messy, try to have a main build and build your parkour on/in the build, and not floating around. The parkour is not really good, it's a bit varied, but still repetitive, try to vary your blocks through the map, and not using one block in one part and never using it again, also just so you know, adding a carpet on a soul sand remove the slowing effect of the soul sand.
Thanks for submtting your map, would be really good to see more maps from you !
