Hello covfefecraft, I am sorry to say your map is being rejected.
Theme: the theme is pretty unoriginal, we have a lot of island themed maps already
Build: the build is cute but as I said, we have a lot of island maps already, so we don't usually accept floating island build for maps anymore!
Parkour: The parkour was quite basic, and repetitive in places. You also used a lot of single glass panes for your jumps. which we don't allow as part of parkour due to version issues.
Thanks for taking the time to submit your map, hopefully, you will submit more in the future!
Have a good day, and happy map building- Cele <3
