Hey great to see you submitting, I will be giving this submission a -1 for the following reasons.
The Submission:
Few problems with the submission, you didn't put the right warp name for the warp. Next time instead of /plot home since that is only for you put /plot visit (username) (plot number), Secondly, you didn't put the number of jumps, I counted and it comes out to about 90 jumps which are way too long for a medium map and more in the range of an expert map. Please next refer to the Map Submission Guidelines at the top of the Map Submissions page.
The Build:
The theme itself is pretty original and there have only been a few maps focusing on mushrooms, the build, however, needs improvement. It does not have the main build and most of it consists of just floating mushroom blocks and a line of blocks. Please try to focus your parkour around a build such as a large mushroom island. The water parts are very annoying as it takes a while to swim up them consider removing them.
The Parkour:
The parkour also needs improvement, it isn't varied and needs more than just head hitters, fences, and 4 block jumps, the map has the difficulty of an easy map with the length of an expert. Please consider making the map shorter and adding more varied jumps using blocks such as vines, ladders, and heads.
Please use this reply has a way to make your map better and hopefully, it will get submitted when improved. Have a nice day! :)
