Little tip for next time, usagi has a wrapper above all controls, where you can just do input.pressed(input.Left etc.. https://usagiengine.com/#input) where you can use those and let the player use either wasd/arrows/dpad/joystick on any control of their choice. Also I’d love a restart button that is not ctrl+r as that reloads the page in itself.
Otherwise, neat graphics, cute sounds and a good score chaser idea you have here! Well done.
