Ha, glad you had fun.
I tried to go with something that wasn't you being uninvited (breaking in) or others were (hunt/defense).
As for gamepad controle, mostly did those for the Wife and then kept them in, forgrtting about look inversion 😂
I choose the bumpers so you could use the fire spell or heal without stopping look or movement.
Not sure about Linux but of course I never built with the intention of Linux.
