I think game right now needs ESC menu with options like help,saving and quitting,suicide,game options.Its better designed,because new players wouldn’t know to press S to save,or Q to quit,or remapping keys by pressing ? than 2.Also old players can remap S and Q for other functions.
It can even be changed to pressing ESC then S to save,or ESC ->O for options,making IN query pointless.
What im saying is that this system is fine for a game demo from Whalesdev times,but it really needs a more standart aproach.
