Funny how big mama is willing to accept payments in bugs.
"I want to stay in the room for half a day, here are two coins and one bug."

Its called barter and trade. 

No different from turning in broken glass bottles and dirty aluminum cans to a salvage yard. 

IF they can make use of it they will compensate you. 

I recently binded keys like this: z x c v m , . / for skill buttons.
But this rezulted in z being the most pressed button, so I also rearranged calls to `draw_master_hotkey_icon` in code a bit, just so some buttons get drawn in a different order. Now v is the button that gets pressed the most for me, much more comfortable.
Game gives custom meaning to first 4 buttons, during many minigames and sex, so the easy way of rebinding doesn't quite works.
