Hey Naruse, I know its been a while since you created this game but I'm actually part of a company working on developing haptic feedback technology that's designed to pair with the LeapMotion and we are looking to put out a developer kit in the next few months so would you be interested in working with us on developing something like what you made here but with the player actually able to feel what they're sculpting? If that sounds good to you please send me a message.
