AI: The Somnium Files is about a guy with an AI for an eye, and he goes into a somnium and there are files involved.

It bears some similarities to the Zero Escape series, which was made by the same devs, but is in a completely different universe and features a new cast of characters.

The gameplay of Ai is similar to Zero Escape, in that it's mostly a visual novel with puzzle sections. The puzzles in this one are not very hard to solve, but there are a few things that make them more interesting. First of all, each puzzle takes place in a different character's "dream world"(This is where the "somnium" in the title comes from), gives them all pretty distinct and interesting scenery. All of the puzzles are on a timer as well, which seems annoying at first, but by doing certain actions in the dream you can get "Timies", which decrease the amount of time your actions take. It gives you a little more to think about, balancing your time with the Timies you have while you work on figuring out the solution to the puzzle, so it's not as straightforward as interacting with random stuff in the room until you get it right.

The biggest issue I have with this game is the pacing of the story. The writing is pretty good, and most of the characters are actually quite likeable, but it feels like the plot kind of goes nowhere for half of the routes. It's set up at the beginning as a murder mystery, but you don't find out very much about the murder until way later on. The "investigation" mostly consists of going to places on a map, and talking to people who usually don't have any important information for you, and then the next plot beat happens. Like I said, the character writing is not bad, but it's kind of a bummer that the last two routes are the most interesting. I thought the resolutions to the mysteries were fine, and the ending was pretty satisfying all things considered.

I definitely enjoyed Ai quite a bit, but I don't think it's as good as some of this team's other work. If the story were a little more focused, and maybe with a different route structure, I think this could be a really great game.
