Hello FireWolf1985,
I regret to inform you that your map is being rejected.
The theme is original, well done.
The build is a concern. It's quite plain throughout, and could benefit from way more details throughout. The interior stays pretty similar throughout with no change in design at all, and the ground on the inside is also quite plain and doesn't make sense with your build.
The parkour has some variation throughout, but is repetitive with ladders, water, and vines in particular. In addition to this, a majority of your map is skippable. This is due to; lower water placement (which you can skip with 1.16+), and low ladder placement. You can skip 90% of the parkour. You can also walk across the roof without doing the rest of the side parkour. Make sure you test your maps for skips before submitting. This map also feels too easy for the hard difficulty.
Thank you for submitting this map, I would love to see more submissions from you!
