No Sleep for Kaname Date is Spike Chunsoft’s latest entry in the AI: The Somnium Files series, but unlike the previous two titles, this one was not written by series creator Kotaro Uchikoshi – and fans of his work will notice immediately. It is also not the third numbered The Somnium Files entry; No Sleep for Kaname Date instead comes across more as a gaiden game – an extra story designed to be enjoyed by fans of the series. With this context in mind, the game itself does its job superbly and provides another fun mystery to solve.
Despite being a game with lower stakes than its predecessor, being a side story and all that, No Sleep for Kaname Date‘s premise is rather bombastic. Iris Sagan, the rising internet idol A-Set, has been abducted by a reptilian alien and is forced to participate in the Third Eye Game. Iris has to solve and survive each escape room until series protagonists Kaname Date and his AI companion Aiba can locate and rescue her. The opening sequence goes hard and introduces the sole new mechanic of the game – the Escape Room puzzles.
The Escape Rooms are exactly as you’d expect an escape room to be – big intricate puzzles. Each one is set up differently, but the basic mechanics involve finding items and solving riddles in order to learn how or where to use those items. It’s kind of similar to the Somniums of the previous games, which are also back, but without the demanding time limit.
For the first time in the series, players take control of Iris herself, and she has a much easier time in these Escape Rooms than Aiba ever did in a Somnium, able to ask for hints or use the new search functionality, only available on lower difficulties. On the topic of difficulty, No Sleep for Kaname Date is actually easier than both previous entries, even on hard mode. The Somniums can be quite stressful the first time through, but outside of this the characters tend to voice their thoughts and theories quite openly, providing ample hints on where to go next.
The handholding is just one factor that makes it clear there is a different writer for this game than in previous AI: The Somnium Files titles. Another is how flanderised some of the characters feel. The words “Atami” and “porno mag” may be heard more times than a player has ever heard in their life, references to some of the funnier parts of the first game used here as obvious fan service.
That said, a lot of No Sleep for Kaname Date feels like it was made for the fans. While the second game, Nirvana Initiative, went out of its way to write the story in a way that would not require the first title to be played to be enjoyed, this one very much assumes players have already experienced them. Set shortly after the original AI: The Somnium Files, No Sleep for Kaname Date goes out of its way to expand on some off-screen events revealed in the second game. This is appreciated, as it did feel like Nirvana Initiative‘s aversion to any story beats from the first title brought the former down a bit.
It is also fun to be in the shoes of Kaname Date once more. He was absolutely the highlight of the original entry, one of the most enjoyable protagonists from this genre, and the sequel’s decision to replace him with two separate protagonists was one of that game’s weaknesses. While both Ryuki and Mizuki were fun in their own right, their split screen time meant neither got the development that Date received in the first one. Plus, Date and Aiba’s chemistry is another big appeal of the series and that is back in full here.
While it is a simple, more straightforward and shorter game than the previous two were, No Sleep for Kaname Date – From AI: The Somnium Files is still a very enjoyable adventure puzzle game. It has a ton of comedic moments and a pretty good story that’s grounded (structurally, not actual content-wise) when compared to the wild storytelling of Uchikoshi’s duology.
Ultimately, this is a gaiden game built upon the engine of Nirvana Initiative that reuses as many assets as it can from the first two entries. It tells a new story specifically aimed at series fans, almost exclusively using the exact gameplay that those fans enjoyed.
