Hello FluffyCat2764,
Unfortunately, I will be Rejecting your map.
The theme is original, however it's hard to tell what the theme is meant to be, especially by the build.
The build isn't great, as it's hard to tell what it is. Try to have one or two main builds in your map that is relevant to the theme, then implement the jumps into the build.
The parkour is very repetitive, as you grouped the jumps. What I mean by this, is that you would have a section of just normal blocks, then just pistons etc. Try to mix up your jumps more throughout the map, as well as experimenting with a larger variety of blocks and items when building jumps, as this will make your map more enjoyable to complete.
Most of the jumps are floating. Try to avoid having jumps floating around the void where possible, and implement them into the build, as having an excessive number of floating jumps can make your map look quite messy.
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.
