It was nostalgic and retro, but would become so much more with a bit more story, characters, and a larger world. This could easily expand into something very zelda or final fantasy-like.
Also, I have hints on how to get each ending for everyone who doesn't want a direct walkthrough:
Troll ending: eager but bumbling mercenary, you get greedy when the guard asks you to take out just the bridge troll...
Old Man ending: vicious mass murderer, you wouldn't stay your blade even to the elderly.
Knight ending: Chivalrous and well mannered, your discipline causes you to follow orders to the letter.
Duke ending: a dastardly and cunning bastard, you would love a shot at the duke's crown, but he's a bit too good with a sword...
