70. S3 Tower of Revival – Blue
The 1st room into the red-&-gold snake door has a cool arrangement, especially the part where you climb up a ladder to loop around from the left crisscrossing the ladder thru a thin passageway as flat Wario, & the challenges where you have to quickly climb up, slide into a niche, & jump before the smashers fall & quake the ground are rare ’nough to feel fresh.
Unfortunately, the designers for some reason felt the need to put the blue key in a niche you have to fall down into & then fall back down to the start, making you redo the aforementioned puzzles again.
