just got a chance to try this out and i like the idea a ton!
if you're amenable to tweaking some of the controls, that could take it up a few notches.
right now, the crank feels underutilized. my first impression was that the goalkeeper should be controlled with the crank, but that was before i saw that there is a paddle/wall that can be controlled with the crank. i still feel as though the paddle is not as responsive as it could be.
the paddle is responding only to the direction of the crank movement and not the speed of the rotation. using the crank for analog control of the paddle or the goalkeeper (with variable movement speed) would make this a much more engaging experience
thanks for sharing your work!
