First off: this game is old, but absolutely playable in 2022. It has almost no jank and the experience is smooth through the GOG installer. This game is an extremely immersive puzzle solver, with a great story and beautiful graphics. It's also pretty hard: you'll need to pay very close attention to all the things you see and hear throughout the game - all the senses available to the developer are used to full effect. Often I would find myself going out on a limb based on something I spotted earlier - and find it was the intended solution. Very satisfying! One point: this game is occasionally obtuse. I solved every major puzzle without hints, but I got stuck for some time in two places because I simply had not noticed a visual detail or clickable location. So my advice is click EVERYTHING that looks like a button, and [HINT AHEAD] open and close every door from every possible direction. This game is comparable in difficulty and satisfaction to modern puzzle adventures like Obduction (same developers) or even Outer Wilds, though it lacks the emotional connection I formed with the latter. Worth a try!
