I have been obsessed with this series since the first Hard Puzzle came out. I have to say that the atmosphere of this installment is a little dark for my taste, but the solution makes sense (or as much sense as is possible in a surreal game like this!) just like the two games before it. Aside from the monstrous atmosphere (which I did not care for), this game was very satisfying to puzzle over and solve. Thanks Ade McT!
