Hello Monkey_King09 and ImAang,
Sorry to tell you that your map is being rejected. The main problem with your map is that the main build cannot be pixel art. This is to encourage creativity and avoid a bunch of really similar-looking maps. Please make sure your build is 3D, or at least not one block thick.
In future submissions, I encourage you to use different types of blocks in your parkour like ice, fences, player heads, panes, etc. This makes the parkour more fun and interesting to play. Your parkour was mostly normal blocks, which is not what we're looking for. [Tas]
Thank you for submitting your map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
