I can't progress past the Silly Troll because I accidentally pressed down before picking up the key and the troll's arm was already dead. Now the chest is already open when I go back so I can't get a new key.
It's a decent game if you treat it like an idle game. Set up an autoclicker to automatically go the next game and just let it accumulate materials and gems and it's not bad. It would be torturous to actually play it to completion, though.
there's another setting for actually turning it on/off. did you click that?
