Hello!
Unfortunately, your map is being REJECTED.
The theme is overall is somewhat original, so good job on that.
The build is where the main concern comes in. The waterslide itself is quite basic and lacks in a lot of detail/depth. The build overall is quite basic. In terms of the parkour pathing, some of the parkour does stick out quite a bit on the build.. especially the slimes at the end. I would suggest trying to incorporate the pathway into the build better so that you can "hide" the slimes that currently stick out on the build.
As for the parkour, it fits the length and difficulty of an easy map, so good job on that! Similar to mentioned above, it is also quite easy to clip the top part of the second slime
We hope to see more maps from you in the future!
Have a good day/night
