I regret to inform you that your map is being rejected.
The theme is unoriginal, as we already have a map with the same theme with ores (2DMC.) Before creating a map, please make sure that the theme has not already been done before by going here: https://manacube.com/threads/parkour-list-with-theme.20194/ The build is a bit plain, as it only contains diamond ore and quartz. Try to use different blocks throughout your entire build! The parkour is also quite repetitive throughout. Try to incorporate different jump styles throughout your entire map! This may include: heads, water, lava, vines, and many more different types of jumps! The length of the course and difficulty of the jumps both fit the easy difficulty, so good job on that!
Thank you for submitting your map, I would love to see more submissions from you! Have a nice day,
Kristina
