hey thanks for playing! Unfortunately you've managed to find a bug ive never seen before with the statue puzzle... the door should not have opened and I have no idea why it got triggered XD its a pressure plate puzzle so you needed to look at the clue on the altar to see which were the correct 2 statues to push onto the correct plates. If it didnt bug out you would have known that the brother got bitten by a snake and you have the antivenom, hence why he slowly stopped responding with voice towards the end.
Also managed to show me a bug in the first room with the mirrors as you did have it right with the first beam but then moved it off which then made it buggy for some reason.
So sorry you had a very buggy game but thank you for playing any way!
