hello iGavin,
I regret to inform you this map is being rejected. The theme is somewhat original, while we don't have any maps with this exact themes there are definitely maps with a similar desert aesthetic. The build is not great, especially on the outside, the redstone is all exposed and clearly visible. The building is also pretty plain inside and out, as it's just brick. There are not really any details to it to make it really feel like a building.
The parkour is where the map really fell short with me. Accessing the parkour presumably through the door code in the tunnel is not possible in 1.8.9, as you cannot crawl. The beginning jumps in the cave are also entirely skippable, as players don't take damage from lava or at all, so you can just swim through the lava entirely. I am unsure of how the map connects to the building because of this, so skipping to the building, the parkour is not mixed or varied at all, as the jumps are just normal blocks and ladders. Try using many different kinds of blocks all throughout your parkour to make a unique and interesting course. You can view recently accepted maps at /warp beta on the server, or the Accepted Maps subforum to see visuals of our current mapmaking standards.
Thanks for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
