Hello iS5D,
Unfortunately, I will be Rejecting your map.
The theme is original, but the build isn't great. It is accurate which is good, but as others have mentioned above it is very flat and pixel-art like, I know this is inevitable though considering the theme.
The parkour has some variety which is good, but a lot of it felt repetitive, especially with ladders. Try to mix up your jumps a bit more throughout the map, as well as using a larger variety of blocks and items to create original jumps.
The length and difficulty are good for a hard map.
Thanks for submitting your map! I hope to see more maps from you in the future.
