I really like this concept - good start! I was hoping this would support VR/Oculus Rift DK2 but it was fun to mess around with regardless. I had some difficulty gauging how far away from the keys my fingers were and as a result ended up frequently swiping the keyboard. It might be helpful to have a depth cue when a finger comes close to a key (such as a dot that gets bigger on the key, or a hairline that connects the finger with the nearby key, or a light on the tip of the finger that reflects off the keys, etc).

Great Job! Very fun to play!

Hard to play. But I still like it.

johnjoemcbob, thank for your comment!

Yes, currently my ability playing is captured too )

My friend, that knows how to play on the piano can too play with this app. It's not easy, but possible... In the future we are planning to improve this app.

One of the biggest issues - efforts keystrokes. And also of course - number of available octaves, it's possible to solve with Oculus Rift, but I want to make this app self-sufficient only with Leap Motion.

I can't play the piano and this game really captures the essence of that! Haha.

Seriously though, this is a very good prototype for only three days work, well done!
