I don't know if it's on my side only, because I'm using Opera which supposedly isn't supported by Unity WebGL (but I can still play it), but every time I shoot the ball, it counts as a new ball, the next life. This is good until you drain your ball early, and as the game thematically puts it, "YOUR SOUL IS TOO YOUNG TO REAP". Then the Try Again timer starts over, and I can keep draining my ball, and I'll have infinite lives...albeit on a short timer.
