I really like the music and character design but I couldn't play the Alpha. My mouse cursor kept disappearing and my keyboard actions didn't seem to register. I have a touch screen on my PC it didn't always register my click events. Maybe you could do a debug build with Node Webkit? Or at least not hide the cursor. Also it looked like you were a couple of version behind on Node Webkit.
Thanks for commenting, we're updating NWJS and making more clear how to play with the keyboard, the game right now is designed to work with a physical mouse, sadly we don't have a touch screen to test but we'll see what we can do in the future.
