Very creative concept! It reminds me of games like QWOP or that vr russian roulette game with manual hand controls. This was the best knot I could tie. Look, there's a loop in it!
I really like that you can change the key binds, though I couldn't set one of the left hand fingers. The music is great, also the SFX.
One thing I would change is to have WASD+QE and JKL; as the controls for one hand, then have a key like SHIFT to switch hands. That way I wouldn't have to develop muscle memory for so many different keys. Realistically I would never be able to control both hands at the same time anyways. I also wish the camera could orbit around the shoe and zoom in and out with mouse controls.
