Go Deep

Click to start playing, pause, and continue playing. Right-click when playing to speed up the game manually. (The game will also speed up on its own over time.)

Health is tracked at the top of the screen (starts below full) and is lost by crossing walls. (There is a bit of a grace period for crossing a couple walls in rapid succession, but it's not something to count on.) When all health is lost, the game pauses itself: reposition the ball while paused with no health penalty and click to continue playing.
