Love this! Better than Myst, I'd say. Reminds me a lot of The Room series.

There's no hand holding: you're just exploring a big mansion with lots of secrets, nooks, and crannies. So hard to come by these days... Click EVERYWHERE. I didn't pay that much attention to the story, but the puzzles and the exploration are very well-made. I also love the fact that it's point and click: no nausea, and runs on any old PC.

Pretty good overall, HOWEVER.
Some of the design choices are really baffling to me.

Making the collectibles mandatory in order to finish the epilogue is quite annoying, especially because they have not been advertised as being important throughout the game.

Also some of the puzzles where multiple pieces turn upon using a button, are imo too difficult to solve without relying mostly on luck (which makes them tedious to solve).
