Here's "Bowser & The Towers of the Hound".
Probably my most elaborate level yet. The most challenging, but also with the most secrets and alternate paths. If you look hard enough, this level can actually be quite fast and easy. As the name states, it's a Castle level, ending with Bowser himself!

EDIT: Slight graphical glitch removed, so new code. Just in time, nobody played it yet .
