This is such a wonderful game ... I have hit only two glitches all the way through, one was where I got stuck coming down a staircase and couldn't move, and if I'd had sense I'd have used a magical ticket to get out of that. The other one, just happened, is weird ... after completing Boss Rush 3, every time I get into battle it says my condition is "petrified," and the sprite is showing in the petrify condition, but my speed isn't affected. Unstone potion does not help. I can't recall if I was petrified at the end of the last of the Boss Rush battles - maybe.
Like I said, it isn't affecting anything (except nobody can really petrify me now), but it's just strange.
AWESOME

Edited to add: I'm back to "good" condition in battles. Didn't see when it happened, but it's a relief.
