Whoa, greatest thanks for such detailed response! I didn't hope someone find the deepness but try to put it in anyway.
The internals of mechanic is pretty simple. Each bubble put value in shared "pressure" level. Depending on pressure level the distraction (shown at the top of screen) changes. So if you keep number of bubbles low, distraction decreases and raises if the pressure is high. Low level of distraction (indicated as calm face expression) shows enlightenment. The time spent in enlightenment increases final score. High level of distraction (when the indicator is shaking) turns on the gameover countdown.
Different effects of bubbles is just different value of pressure for now. Toilet bubble has highest pressure value. I had planning to add funny outcome like the puddle should appear after disbanding the toilet several times. But as usual the time run out earlier.
Thanks again, you motivated me to keep improving the game. I guess i should just disable controls on gameover screen for several seconds, what do you think?
