Hello ir2153,
I regret to inform you that your map is being rejected.
The theme is not the best, as it is based off a single minecraft block, so it is kind of plain.
There is no main build, which is a crucial issue. Every map needs to have a main build; something that your parkour can build off of!
The parkour is also quite repetitive throughout, so please be sure to use different varieties of jumps throughout your entire map! This may include; fences, water, heads, vines, glass, and many more different types of blocks depending on your theme. The length of the course does fit the medium difficulty, but the difficulty of the jumps is inconsistent.
Thank you for submitting this map, I would love to see more submissions from you!
Have a nice day,
Kristina
