Wow this is really great! A very Legend of Zelda: A Link to the Past feel. I loved the puzzle bits, and the creative weapons(a crystal ball and a wand, I believe they are?).
I did have a problem. After I completed the game, I wanted to play through again. When I pressed c to start the game, I spawned in the wall and couldn't move anywhere.
I talked more about this game in my blog also: http://pajamagaming.blogspot.com/2017/03/browser-games-3.html
