From Micropig Gaming:

I’m working hard on the next version of Breath of the NES, my Zelda fangame 😊 Now including a ton of graphical improvements and gameplay improvements! If you prefer a classic NES style look, though all of the visual effects can be turned off!

I’m also currently looking for some help doing pixel art and music for the game. Please contact me on twitter if you can help.
