I'm always impressed when people make genuine retro console software, so that gets a lot of points from me. This is a neat little zelda clone, it definitely looks and controls nicely, though the lack of sound makes it feel a bit empty. I did like what you were going for, but I couldn't complete the game, because enter certain screens caused the player to get stuck on an environment object, and become unable to move.
Side note, something I found fun, is that using a turbo button for the attack while spinning lets you attack in all four directions at once, take that, slimes!
