Ideas for the visual changes after each encounter without clothes:
1 Circle; Blushing, breathing is faster
2 Circles; Blushing more, Breathing is much faster, more exhausted looking animations for walking and idling
2.5/3 Circles; Blushing even more, Breathing is way faster, Mox looks like she is just barely holding herself up.
Negitive effects for each phase:
1 Circle; Bullet spread is increased
2 Circles; Walk speed is redused, max stamina is redused
2.5/3 Circles; Walk speed is redused more, Max stamina is halved,
Stamina recharge rate is halved
