I think there is a lack of signs here and there, for example I first didn't know I could kill the crows by jumping on them, and I was lost some times as there was nothing to indicate where I should go.
Also, be careful when you use buzzer like that, it can easily hurt your player's hears, especialy on a short loop.
Also, I couldn't use the menu properly since my mouse disappeared and I had no way to select something.
Also, that's just a idea, but since roles are reversed, shouldn't the enemies look the other way ? They probably expect the hero to come, and not necessary the princess to escape.
