Hello Blurpyfied,
I regret to inform you that your map is being rejected.
I have sent you a DM with a more detailed explanation but TL;DR the parkour is very underwhelming and needs more variety, particularly in the beginning.
(Note that while the other BowsersCastle is accepted, you are welcome to resubmit this map, it just needs a name change.)
Thank you for submitting this map, I would love to see more submissions from you!
