Mario themes are pretty overused but pokey is original and cool
The general build is good, but you could probably have some more block variation and details.
I think the parkour is an issue because of repetitiveness, you should use some more variation in the jumps.
(My tip to you is to look at the recent added maps and take inspiration for you parkour from them)
-0.5 from me, but if you fix the parkour it'd probably be accepted ^^
