Hello,
I regret to inform you that your map has been REJECTED.
The theme is unoriginal as we already have maps based on fish.
The build of your map is a concern. As there are a few smaller builds, most of the parkour is floating which makes it messy. Build a larger main build/island so that you can path the parkour around the build and add more depth and detail.
The parkour fits the length and difficulty of an easy map so good job on that! The only variation you have is ladders and normal jumps. To add more variance, use blocks such as: fences, heads, water, trapdoors, daylight sensors, glass panes, etc. This will make the parkour less repetitive.
We hope to see more maps from you in the future!
Have a good day/night
