Very impressive and cute. I do find it a little slow to redo everything so maybe doors could stay open and you keep the sword? The only other thing I would suggest apart from regulars of audio etc (Although that might be quite difficult based on how you made the game) would be making the walls automatically appear. I have to constantly keep running through corridors hitting right or left every step to make sure I didn't miss a path. Otherwise very good game and admirable from its constraints.
