Hello A1TheGamer,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are many biome/nature themed maps already. I would recommend referring to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original. (CTRL + F on windows and command + F on mac to search for specific themes)
The build isn't bad, it does look a bit strange from the exterior, but the details of the interior do look nice.
The parkour is quite repetitive. You did incorporate it into the build well, but it still felt a bit boring as most of it is normal block jumps, due to the nature of the build it would be difficult to change it significantly, but I would recommend experimenting with a few different blocks and items to create more enjoyable, original jumps.
The difficulty & length are good for an easy map, but it did feel a little bit short, so it might be nice if you extended that a bit more.
Thanks for submitting your map! I hope to see more maps from you in the future.
