Dang, nicely done! If you listen real hard when you get into that nook, you may hear something, as well...
There are 4 or 5 more secrets in the game...some discoverable, like that one, and some random.
I honestly thought they'd just go unnoticed after the jam is over and the game got its handful of plays. Good job at finding one!
