A bit long, but figuring out each step was still fairly rewarding. I also saw in the game credits that the designers thank Jesus, and it shows in the fact that you use the Bible in one of the puzzles, which I thought was cool. Gameplay was pretty good. The transitions aren't as smooth as some other games of this type, but once you get used to them, it's not too bad. Sometimes it's not very intuitive trying to figure out what you can click on, or where you can go in a scene, but you kind of get used to that, too.
Graphics are realistic, but somewhat grainy.
Still, they are good enough to do a good job of immersing you into the game. They are no where near the quality of games like Riven, which is several years old, but they aren't so bad as to be distracting. Sound was probably the worst part of the game. In some areas, the sound cuts out for about half a second every time I move forward to a new screen. Sometimes in the VR view, certain angles trigger music, and if you move back and forth, the music starts and stops as you move past the trigger point.
