Add an out-of-game all purpose game controller where creators can add pause/play behaviors, restart, special mouse commands, and so on. That way you don’t have to add a “transparent object” somewhere in the game.
what is it?
there is a sight where you can make the controller emulate (or however its spelled) a keyboard
Seconding this - while I usually place mine on the GUI, a game controller would be very useful.
not sure. mhx mentioned it before
