It's a pretty poor zelda clone.
First of all, they day and night thing seemed pointless, and the game is full of glitches.
And here is a big one, Why the fuck does he have a shield if he cannot block with it, I understand the look you are going for, but don't tease me with cosmetic equipment, if his only ability is slash a sword, he should have ONLY a sword.
Finally, there should be a tutorial, it took me twenty minutes to figure out how to open and close the menu, however the blame for that is partly on newgrounds, for the inability to read your description while the game is running.
