Hello fribe,
I'm giving your map a -1 for the following reasons,
The theme is okay, there aren't any maps that are the same build as that, but there are many that fit the Mario category. The build is quite plain, which I know when building characters like those, it's hard to add much detail, so that isn't a huge problem.
The parkour is alright, the start especially with all the barriers is quite confusing, maybe adding signs saying that the carpeted areas are blocked off? Just adding something that maybe makes it a bit clearer what you're meant to do. For the rest of the map, the jumps are pretty repetitive, I would suggest using more variety in the jumps, rather than mainly using ladders and single block jumps. Also as I mentioned previously, maybe adding more direction to the inside part of the map since that could come off as confusing for some.
Good luck! :)
