Hey there, portal_ninja
Unfortunately, I will be REJECTING this map submission.
Theme: First thing I noticed is your theme, unfortunately from my point of view your theme isn't really that original, we've got a handful of parkour maps that are related to the nether and have nether-related things in them sadly, for example, NetherBlocks.
Build: Your build, from my perspective visually your build isn't that attractive, it does resemble a nether fortress but the scale of the build isn't that accurate to a nether fortress and you didn't use any interesting patterns or any interesting block designs which could have made it more visually attractive and representable.
Parkour: Your parkour, after checking this out personally in-game unfortunately your parkour unvaried which makes your parkour map submission very bland/repetitive and doesn't really provide much enjoyment to it. I recommend adding more interesting parkour blocks/jumps that could make it more interesting, for example, flower pot jumps, anvil jumps, chest/enchantment table jumps, etc.
Thanks for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
