It's on stable state now that everyone can test tight control scheme:
mym-tight-control.netlify.app
Arrow keys
Left, Right key to move cursor side to side
Up, Down kwy to tilt marbles within column
Space bar - Center line shifting
Ctrl or Z key - Rotary cyclic around center
R key - restart
Almost forget to mention that both "worm holes" serve as warping gate to make warp-shifting "physically sense".
