Really nice attempt
I'd really like to see more with this. As it stands, there are just too many glitches and problems for me to say it's great, but it probably wouldn't take too much to fix them and then update your submission.
I played classic as Link and there were a couple things that made it unplayable. The first thing I noticed was the fact that he had the same sound for every time he jumped. And then on the break the targets part, the same "Heyagh" played over and over and it really got annoying. In the game, I think they gave him a little grunt and I think you could've gotten by with that as it's not as long and doesn't stand out that much.
The second thing, that really hurt the platforming aspects, was the fact that when you turned left and right, your sprite image shifted position, noticeably enough to fall or land off/on and platform unintentionally. It made maps with platforms built in it (a lot of maps) much more frustrating.
The controls are intuitive enough, the gameplay was fun enough, and you really did a good "port" of the game with your artwork for the maps and your usage of sprites.
It's just not as great as it could be, in my opinion. It needs some serious tweaking, then it could be really good. Decent enough job as is. You get a 6/10, slightly above average.
