"These are a few of my least favorite things"

Found on Reddit (in one of the better corners) on the Mario Maker sub:

Instant-death doorways and blind leaps off ledges
Thowmps hidden slightly outside of screen edges
Quick moving platforms on tracks with Boo rings
These are a few of my least favorite things!

May post another level later today.  I've got like four WIPs, none of them seem good enough to upload yet.
