Hello Marjo03,
I regret to inform you that your map is being rejected.
The theme is original; we do have a toxic-related map, but it is executed differently.
The build is somewhat accurate; however, it is a bit flat, so make sure you give it some more shape/depth and add some more details as well.
The parkour is repetitive throughout, so make sure you use different types of jumps throughout your entire map. There is also a lot of floating parkour present (jumps that are not attached to your main build) which makes your map look messy. The difficulty of your map is inconsistent with the length fitting an easy map and the actual jumps being more difficult.
Thank you for submitting this map, I would love to see more submissions from you!
