Hello,
Unfortunately, your map submission is being REJECTED. Here is my input:
Theme: We do not have any yin/yang themed maps (we have some Oriental-themed maps like Zen, ZenGardens, Oriental) but this is different enough from those to be acceptable - nice job on choosing an original theme!
Build: The build was too much of pixel art to be acceptable on Manacube - try to make your builds 3D and well-detailed for future reference, as it allows you to incorporate the parkour into it instead of being so floaty and looking messy. It was definitely accurate to your theme, so nice job on not making it look terrible.
Parkour: The parkour was quite repetitive - try to use a wide variety of blocks (i.e. anvils, heads, ice, soul sand, flower pots, lily pads, water, etc.) to make your parkour more fun and interesting to play. The parkour was the proper length of an expert map, but it was also too easy - make sure your map is up to the standards of an expert map.
I'd love to see more submissions from you in the future, and have a great day!
