Hello Morphoz_YT,
Unfortunately, I will be
Rejecting your map.
The theme isn't very original as there are many minecraft/islands themed maps. I would recommend checking the document linked in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build is quite small. In the future, try to have one or two main builds that are relevant to your theme, then build the parkour into that, rather than having the parkour floating between smaller builds as this can make your map look a bit messy.
The parkour has variation which is good, there are a few sections that felt a little repetitive though so try to keep up the variation throughout the whole map.
These vine to ladder jumps are also impossible -
The length and difficulty are good for a medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
