Hey Fw5,
I'm sorry to have to tell you that your map has been REJECTED. The theme is not very original as we have two other slime-themed maps and this one build isn't bringing a different take on the theme. The build is mediocre, lacks block variation, and isn't very original. The PK difficulty fit the easy difficulty but it was rather extensive for an easy. Also, the variation was not the best. When making parkour, you should try to use as many different blocks/jumps as possible to make it an enjoyable experience. I hope to see more map submissions from you in the future!!
