+ On collision between A and B (when player pick up a power up)
+ Var = 1 (this is level of power to upgrade in game store)
-> Do something (when level is high do something better)
So its my only idea how behave player when have upgraded level "var 1,2,3 etc.
It is inseparable part of the game and must be, even if this cause performance problem, I have no a better idea before how to minimize it.
