So many bugs...
* I got stuck on top of a treasure chest and couldn't jump off - had to F5 the page
* A chest appeared on the same square I was standing, then I was outside the walls and couldn't leave the room - had to F5 the page.
* Got the best sword, shield and finally made and equipped the cursed ring. Beat the boss and lead Hilda out... but got the "Hilda remains in the castle" or whatever-it-says ending.
You ever heard of playtesting?
