Hello,
Sadly your map is being REJECTED.
Sadly this theme is unoriginal as we already have similar maps.
The build has a lot of islands which causes a lot of floating parkour, leading the map to look messy. Build a main build/island where you can path the parkour around it. Use blocks such as heads, glass panes, slimes, daylight sensors, cocoa beans etc to add more variation to your parkour. Currently, the parkour lacks variation and is repetitive.
The majority of the parkour is too easy for a medium map, sadly.
