Hoi ilovetoto,
Sorry to tell you that your map have been rejected.
The theme is sadly not good, as we already have some "Earth/Planets" themed maps (Globe, Planets, EarthCenter), be careful next time and feel free checking the parkour list on the forum ! The build is also not good, the parkour make the build quite messy and then quite unattractive, try building your parkour on/in the build like you did at the end, and not floating like you did at the start/middle. The parkour is not really good, while the parkour is a bit varied (you used some slimes and ice), I still think the map is a bit repetitive, as there is mostly normal and ladder jumps, try using different blocks (like soul sand, water, vines, fences..) through the map and not once/in one spot.
Thanks for submitting your map, would be really good to see more maps from you !
