Hoi shinx,
I will be giving your map a
+1, the theme is original, as there are no deltarune maps. I had to search the character of the game as I dont know it, and looking at the build, its a nice representation of it. About the parkour, your map fits the medium difficulty nicely,
(even though the cyan wool is mean x)), it is varied, although I think some parts look a bit messy.
another great parkour :3 congrats
¡Good luck! <3
