Move yellow blocks - right joystick button and left joystick button alternately, as switch on/off;

Tested with DualShock 4, but should work with all controllers.

Keyboard is not supported.

Note: Game has web export, but controller vibrations are not working, and graphics look a little worse, at least for me. Desktop builds recommended.
