Hello!
Unfortunately there are a few main issues that make this map unlikely to get accepted. That is the theme and build. Themes centered around rainbow are not original at all, as they have been done a lot. For this reason alone, your map would probably not be accepted. The build is also nonexistent. It’s just floating jumps and platforms. Which is not accepted as a build.
aside from those, the parkour is also quite repetitive, but the parkour is not the main issue here.
for these reasons, I will be giving this map a -1
