I'm happy to tell you that I'll be accepting your map!
The theme is original, as we don't have any ping pong maps yet. The build looks good, and it's accurate to the object. The parkour is nicely varied, and you included some fun and original jumps. Your map fits the easy difficulty in both length and difficulty decently, so good job on that! I did have to rotate your map by 90 degrees, as it was in the wrong facing for the easy difficulty.
