Yay, my game has been greenlit!
There is actually a funny backstory to this.
I was into IoT at the time and has just received a Leap Motion device on the promise of submitting something to Hackster.io (an IoT webite) I did and this was the game. The IoT angle was a power glove that I connected to the Unreal Engine Bombardier game.
You controlled your bomber with you hand and when something happened, the power glove would vibrate.
The glove (a old cycling glove) had a vibration motor hot glued to it and that was connected to a micro controller and that was then connected via USB to the PC. The USB was driven by a DLL that was then accessed via the game.
Now this might seem a bit out there. But given HTC is making their VIVE system a bit more open, there might be demand for IoT like mashups in the future.
