That was a pretty long waiting. Well, the final stage has some strong and weak points. I'm gonna start with the latter then.
That segment with key jumping felt kinda bland and repetitive. So much could've been done with low gravity IMO. The part where you had to summon a Wiggler in order to hit the invisible coin block so another Wiggler can get past there felt kinda slow.
Regardless of anythning, the stage was pretty well designed and was creative with its ideas. You usually design levels well so you don't have to worry about improving what could've been done a lot better.
I have a Discord server as well!
