Hello gavkoCZ,
I regret to inform you that your map is being rejected.
The theme is unoriginal, as we have several maps relating to trees (SpookyTrees, Tree.) However, the idea of incorporating it with a monster is original, so good job on that!
The build is a bit plain, and it also contains some floating islands, and those aren't really the best thing to use when building. The Tree Monster itself isn't the main focus of the map; when I tested it, I barely even saw the actual monster. Try to focus the parkour more on the main build next time!
The parkour is a bit repetitive in certain spots. Try incorporating different jump styles throughout the entire map; you can look at recently accepted maps for examples of these! There is some variety, but like mentioned, it'd be nice to see it through the whole thing. There's also an abundance of floating jumps (jumps that aren't attached to the build), and these can make the parkour appear messy. The map feels too short for a hard or an expert.
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
