How to solve the secret of the old gate?
each symbol has their own thing you need to burn to be able to open it, the one at the mansion you just burn all the nuts, the symbol on the road to the witch you will see that a red leaf appears flying from the right well you have to grab it and to the fire it goes, now the one in the forbidden forest will a have a lot of fireflights in it which you cant catch but they will ran away from your mouse so juts guide them to the fire (All symbols light when the task you need to do to activate them its complete so just keep burning the things I said until the symbol glows). After all of that just go to the gate and interact with anything on the other side and I mean ANYTHING. The scene triggers when you leave after doing that.
