Hello i_Cryptide,
Unfortunately, I will be Rejecting your map.
The theme isn't original, as there is already an ice mountain map (IceMountain - Hard) I understand the maps do look a bit different though.
The build is accurate, but it does feel a bit simple. It's good that you used the snow to create texture, but the actual shaping of the mountain feels a bit off.
The parkour is quite repetitive. You had a few different jumps throughout, but there were a lot of areas that were just normal blocks repeated. Try to mix up your jumps a bit more throughout the map, as well as using different blocks and items to create more original jumps, as this will make your map more fun to complete.
The length is good for a medium map, and the difficulty is good for an easy/medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
