Hello <3,
Unfortunately I'll be giving this a -1. The theme is unoriginal, as there are already several maps that are based on multiple colors. About the build: It is a bit plain, with only a few different varieties of blocks being used. Consider adding more details next time. The parkour has a lot of floating jumps, and those are, sadly, a big negative (jumps that aren't attatched to the build). The parkour itself could use more variety as well. I believe this may fall under the easy category, but I'm not sure.
I wish you the best of luck! <3
