Hello llighty! I will be rejecting your map, unfortunately.
The theme is definitely original, as we don't have any "Piffle"-themed maps, and I can't think of any maps that looks particularly similar.
The parkour is well-varied. However, it's a bit too difficult for an easy; I think the difficulty suits Medium perfectly except for one or two jumps, but the map isn't quite long enough to warrant it being accepted as a Medium. Otherwise, though, it's still fun and original.
The build doesn't look much like Piffle, in my opinion. Comparing the build with Piffle images, I do see what you were going for, but the build looks rather small and cramped, and the loss of detail is very visible, especially in areas like the face.
Thank you for submitting! If you have any questions, feel free to message me in-game, on the forums, or on Discord (MCBYT#2023).
