Hoi TheBDom,
Sorry to tell you that your map have been rejected.
The theme is not really original if we look at the name, but it's even less original when we check the build, because there is already some "Rainbow" maps, so please be careful next time ! The build is not really good, it's pretty plain and unattractive, mostly from outside. The parkour could be better, it's a bit varied at the end, but still pretty repetitive.
Thanks for submitting your map, would be really good to see more maps from you !
