for the blue key they dont have to click it if im correct, just be in the screen while the person who's getting the keys clicks it... and more than one person can collect keys, if all of them can, tell em to go for it, so that you dont have to do the quest all over again in case you wanna go again

for the green key its 1st option, 2nd option, 3rd option, 1st, 2nd, 3rd, 1st, and 1st i think? up down turn up down turn up up?? o.O i forgot

and maybe a mod can move this to game mechanice and strategies? o.O
