Overview
It’s always interesting to see what a series might try to do next but when it comes to the AI: The Somnium Files players certainly never know what to expect. This twisting and turning puzzle pair of puzzle games has always been incredibly odd with its own brand of humor and deep explorative themes, but when the next game was announced and lacked the involvement of one of its primary creators and only a supervisory role of another, questions were raised. Combine this with the fact that No Sleep for Kaname Date – from AI: The Somnium Files is something we don’t see much in game series’ and we already have a rather strange combination. While there may be many sequels and many pre-quels, this one happens to be a mid-point side story rather than any form of continuation.
Story
Almost right from the get go it should be known that No Sleep for Kaname Date is not for those who have not played at the very least the first game in the franchise. It is possible to play this one without playing Nirvana Initiative but some interactions, revelations, and introductions will lack a bit of “impact” without having done so first. In fact, just like Nirvana Initiative, No Sleep for Kaname Date gives players a knowledge check right out of the gate with players needing to type in an answer to let the game freely reveal details from the first title without worrying about obfuscating things or skirting them entirely. Since we did know the answer, we don’t know how this might be presented to those that don’t.
Anyways, No Sleep for Kaname Date picks up sometime, probably no more than a few months, after the events of the end of the first game with Kaname Date, a perverted investigator who works for the secret government organization IBIS alongside his AI-ball (eye-ball) companion that lives in his eye-socket Aiba, finding out that his internet-idol friend Iris Sagan has been kidnapped by aliens and is being forced to play an escape game by the reptilian known as Akemi. Iris must solve these puzzles on her own but is given the chance to contact one other person for help, and she has chosen Date to aid her in escaping from this alien being’s strange plot.
To make things even stranger, when Date and Aiba begin to look into the mysterious disappearance of Iris and try to locate where she was when she was taken, Mizuki notifies them that a strange coffin-like object has been found within a refrigerated warehouse on the docks with the sign “Psync Me” taped to it. With no knowledge of who or what might be inside the pod but possibly having ties to what might be happening to Iris, Date has no choice but to do so and enter the Somnium of whatever is inside to find out. This leads to what ends up being perhaps the most underwhelming, low-stakes, and shortest games in the franchise and probably why it is being treated more as a spin-off rather than a “mid-quel” that it appears to be.
As mentioned earlier it is worth noting that Uchikoshi, who took the lead on the other two games in the series has no connection to this release with Kazuya Yamada instead taking the reigns this time around with the storyline and, thanks to the fact that this is a game all about mysteries and puzzle solving we can’t really go into them without spoiling things, it is worth mentioning that the twists and revelations here are incredibly simplistic to the point that one of the Aiba notes that scrolls on top of the screen from time to time even points out that players probably already know what’s going on before the big reveal. It also doesn’t help that No Sleep for Kaname Date feels more like it was written as a set of two DLCs that were instead combined together with just enough tangential connection to create a coherent storyline.
Now, with all that said, it should be worth noting that while we’ve said quite a few negative things about the way the story unfolds, it must be said that Yamada has managed to capture Uchikoshi’s eclectic cast of characters perfectly here. In fact, the fact that players are able to see so many new interactions between characters here whether it is Date and Aiba’s non-stop back and forth banter, some hilarious reactions and interactions with objects and outcomes depending on choices made during Somniums or escape room choices, or even the two new characters having a chance to shine and we have a storyline that is actually heavily carried by the fact that these are characters that fans of the franchise love. They do a lot of heavy lifting here but it works well throughout every aspect of the storyline, with aforementioned newcomers Hina, the new psync technician at ABIS who is conveniently obsessed with escape rooms, and the reptilian Akemi serving their roles well.
As mentioned before, No Sleep for Kaname Date is on the shorter side, running roughly half the length of either of the original releases which is to its benefit thanks to the lackluster twists but that doesn’t mean that the team at Spike Chunsoft has skimped on the extra content. There are over ten different “alternate” endings that are joke endings, ranging from simple callbacks, or even call-forwards in this case, to entirely off the wall style ones. None of these are canon though one does happen to appear to have quite a bit more too it though at the moment of this writing we couldn’t figure out the final condition needed to unveil it. Alongside these bonus endings are other small scenes that players can unlock that provide some extra scenes for some characters and a few fun perspective mini-novels as well, giving players a wealth of bonus content to enjoy even after the credits roll.
Gameplay
No Sleep for Kaname Date puts a bit of a twist on the usual formula of the past two games, while players will still be finding themselves playing as Date and traveling between locations and using the joycons to examine objects in the environment and talk to characters, including using Aiba’s new “Wink Psync” that fully appeared in the second game as a sample here, as well as occasionally taking part in psyncs that see Aiba being the one in control as she explores the mind of an individual inside of their Somnium, both of these elements actually take more of a backseat compared to the third element that the former Zero Escape team is best known for, escape rooms.
The Psyncs still work the same as before and only happen a few times this time around with Date delving into the psyche of someone with Aiba having a six minute timer where she must break through various “mental locks” by using keys and objects scattered through the Somniums that are incredibly straightforward this time around. Players can use various tools to decrease the amount of time some actions take, giving players a chance to take risks if they don’t know the answer or mess around with an obviously wrong but most likely funny sequence instead. The design and lack of challenge in the Somniums this time around is disappointing in the end and while it is understandable they aren’t the main focus this time around, a little more variation or unique elements like before would have been nice.
Similarly the exploration sequences where Date travels from place to place around the real world to investigate are as simple as can be. These point and click style segments are generally filled with the aforementioned fun engagements with the beloved cast of characters and jokes, a few of which aren’t translated the best, when examining random items in the environment. These tend to be where players obtain “hidden” early endings and random sticker collectables as well. It is also worth noting though that players can “lock” themselves out of fully exploring or examining everything or going to the correct location first if they aren’t careful.
It is the escape room puzzles where No Sleep for Kaname Date really shines and players can tell that the Zero Escape team has put a lot of effort into making these puzzles and riddles really interesting while also trying to balance making them tough but rewarding to figure out. As players progress through the game these escape rooms grow considerably more challenging with more players being added into the fray beyond just Iris and as the player solves clues, gathers items, combines them, and solves riddles, they’ll always feel like they are actually engaged and challenged. In fact, almost every escape room culminates in a timed challenge that players will need to figure out a solution quickly or risk a game over (there are checkpoints in the escape rooms). These timers increase the intensity and even work as a good little play on words as Akemi will challenge players to use their “Third Eye” (get it?) to find a third solution to an impossible on the surface puzzle.
Thankfully, these puzzles can be heavily modified in actual challenge by swapping difficulty levels and if the player does fail, they have an option to knock the level down one step. These difficulty levels dictate how long players can have to solve some puzzles, whether or not a clue can be pointed out to them to examine, or even just straight up point out the solution. In many cases players will be able to figure these challenges out on their own but there are a few obscure ones that might push the limit a bit and we aren’t too proud to admit that for one “third eye” solution we let our allies spell out the code needed. This means that even those who aren’t the best at puzzles can still enjoy what they can solve and still ask for help when needed as characters will only speak up when prompted to, giving a nice balance of challenge and reward.
Audio & Visuals
It is worth noting that we reviewed No Sleep for Kaname Date on the standard Nintendo Switch and for the most part the game still looked as impressive as ever with solid character models that only had a bit of jagged edges at times and great character designs to go along with them. The levels players explore in the escape games are wildly varied and look great but the Somniums are a disappointing re-use of assets and lack the “twisted dream” feeling they used to have. Also, while I am all for fan-service in a game and applaud it, the bunny costume that Iris wears is one of the oddest takes on a bunny costume I have ever seen.
Thankfully all of the English voice cast has returned to reprise their roles in the English dub of the game, including characters that only appeared in the second game. This works great since most fans are quite familiar with them and it makes some of the new interactions even better, especially since some of these characters never talked to one another before. Newcomers Hina and Akemi are similarly voiced quite well and the Japanese voice track is always there as well as an option should fans prefer that route. The background music throughout the game is quite fitting when exploring or solving puzzles and there is even the classic dance number at the end, though the accompanying song might not be quite as catchy as either of the other two in my opinion.
Overall
No Sleep for Kaname Date – from AI: The Somnium Files is a solid side-story/mid-quel for fans that already know what to expect from the game. The storyline is one of the weakest yet when it comes to twists and stakes but thanks to an absolutely wonderful cast of characters that make up for it. The character interactions happen to be some of the best parts of the game alongside some wonderfully challenging escape rooms on a title that is great for fans but doesn’t reach the heights of the main entries.
