Ok, looks nice... box rotates, ball is released on click... hits wall, shatters... rinse and repeat... Something appears to be missing... anyways, love your other work!
When the ball is released on-click, you're supposed to immediately click-and-hold again to activate the walls for the ball to bounce (full red opacity) - and release the mouse-hold to deactivate the walls again. The ball shatters when it hits unactivated walls (zero-opacity red). Clicking-and-holding drains the top bar, each ball bounce refills said bar.
