Not sure what bugs have been reported, but in the beginning town, the first house you come from, the top-right roof tile can be walked through from top-to-bottom. Also in the beginning town, if you keep opening and closing the menu while walking down to the exit area before you're supposed to leave, your character will get locked because all of the controls stop registering. I don't really think anyone would typically do that honestly, but I thought I should mention it.
I did a similar thing in the game "Adventure Time: Secret of the Nameless Kingdom" to break what ground level you were on.

So far your game seems a lot less bug prone than that game was.
