I'm very impressed with this.
The idea of a Plattformers with Zelda-Like Item Progression is pretty neat and I wish I could see a full game of this. I only had a few minor problems, like the hook being pretty counter intuitive, I didn't like the music as much (it was a nice touch though, I understand how difficult it can be to make music in that short of a timeframe at all) and I didn't really feel (small), as much that everything else was super-size. All that is just nitpicking though, because this is a really solid submission of a gamejam.
