Hello Ethanjlong,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there is a very similar map already (
Trash - Hard) Please refer to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build isn't great, it is accurate to the theme, but it does feel a bit plain. I would suggest trying to add a bit more detail to the build.
The parkour is very repetitive, as it's almost all normal blocks. Try to experiment with a larger variety of blocks and items when building jumps, as this will make your map overall more enjoyable to complete.
There are also quite a lot of floating jumps, especially in the second half of the map. Having jumps floating around the build or the void can make the map look a bit messy, so try to avoid that and incorporate the jumps into the build more where possible.
The length and difficulty are good for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
