Hey there,
Here is a link to a unity project, that allows you to play the cyfi game with your own input, I found this useful to test physics and come up with some potential states.
Just open the project in unty, open scenes/SampleScene, start the cyfi SignalR hub and press play.
use the arrow keys , or wasd or a joystick to move
note: the initial startup can take quite long (5minutes) , to download the dependencies.
