You have stunned me!
This is by far the hardest kind of mystery to solve and even though i took a long time to figure out what to do and which room to go i worked it out in the end.And please if someone says that you do not give enough clues,make it even harder and put lesser clues.Wheres the fun if its easy?So what i reccomend in your sequel is mae it even more mind twisting and nerve wrecking.Make it so hard that someone wants to sue you.Other then my compliments and suggestions,i really have nothing to complain about,so keep it up!
