No Sleep for Kaname Date – From AI: THE SOMNIUM FILES Review

 

Gameplay Loop

No Sleep for Kaname Date follows much of the same gameplay loop as you’d expect from previous games. The main new addition are the escape room sequences, which work a lot like in previous Somnium games but with more focused puzzle-solving instead of seemingly random choices. You follow Date and Aiba as they solve the mystery of Iris’ disappearance and abduction into the escape rooms, diving into the Somniums of case suspects to search for clues in their subconscious, and helping Iris solve the escape room puzzles whenever she is able to contact Date from her mysterious whereabouts. 

The main gameplay loop is Investigations, Somniums, and Escape Rooms. The Investigations are first-person, point and click, visual novel-esque sequences consisting of a lot of dialogue between characters. The Somniums are in the third-person perspective of Aiba and allow you to walk around a case suspect’s dreams. The Escape Rooms work similarly to the Somniums in a lot of ways –  you are placed in a strange, unknown setting and have to find clues to get to the end. There is also a time limit in certain cases during the end of the escape rooms.

The main differences are that instead of in Somniums where the time limit is always six minutes from the second you enter the Somnium, in the escape rooms, the time limits are variable and only start ticking down during crucial moments nearing the end of the sequences. This felt a lot more tense than in the Somniums, where time only starts moving when you move around or choose an action. In the time-limited escape room decisions, you must open your ‘Third Eye’ to find a third solution between two seemingly black and white options given by the narrative, which urge you to think outside of the box to finish the puzzles. I enjoyed these timed sequences a lot and found them to be at a sufficient level of challenging without being frustrating. 

I played on the standard difficulty, which was the right difficulty for me, except with a few particularly boring puzzles where the answer was clear but required a lot of back-and-forth checking of items, and I ended up lowering the difficulty briefly and let the game assist me instead to get the puzzles cleared faster. The difficulty settings impressed me a lot, with many options focusing on if you want a story-focused playthrough or a more difficult challenge.

 

Graphics

The graphics quality in No Sleep for Kaname Date aren’t anything to write home about, but the stylistic design doesn’t require very high definition to be effective. Additionally, I am a big fan of the design choices in this series. I really enjoy the first-person perspective during Date’s investigations, which makes the experience a lot more immersive. I also really liked the Somnium designs, which felt confusing and trippy, adding to the sense of mystery relating to solving the Somniums.

Whilst I liked most of the newly appearing characters designs, I really disliked Iris’ redesigned outfit for the Escape Rooms; the accent colour is a glaring bright pink that drowns out her already pink hair. The rabbit paws and feet have weirdly separated fingers and toes, which look more “creepy mascot rabbit” than “endearing bunny girl”, and the extremely low-rise fluffy shorts that don’t look like they are connected by anything to the longer piece of fur cloth with more coverage on the back makes me feel like they couldn’t decide whether they wanted her outfit to look more cutesy or revealing. I know this is a relatively small thing, but for a character I have to look at for the majority of the Escape Room sequences, I really wish they would have chosen a more decisive direction and stuck with it instead of trying to do everything at once with her design. 

Nothing about the sound design particularly stuck out to me. The soundtrack was good but not outstandingly catchy, and there weren’t any particularly interesting uses of sound effects. There is an option for both English and Japanese voices. I went with the English voices as I played the first two games in English as well. While the voice acting isn’t terrible, sometimes the line delivery was a little flat or unreactive.

 

Story/Writing

The quality of the writing in AI: The Somnium Files has always felt mixed to me. On one hand, the mysteries and puzzles are always a pleasure to solve and keep you engaged right up until the end. On the other hand, the character writing and dialogue becomes tiresome after a while. There doesn’t seem to be any interesting character development from previous games, and all of the characters feel tropey and one-dimensional. Iris is the energetic and ditzy idol who keeps getting into trouble, Mizuki is the straight-laced, serious young girl with uncanny fighting abilities for her size, Aiba is the helpful, logical assistant to Date who overexplains everything, so on and so forth.

All of the characters are likeable at first, but once you realise that what you see is essentially all there is to them, they become very boring very quickly. Date, the main protagonist, is probably the best example of this; he is quickly established as an easygoing and laidback character, but that regularly contrasts with the severity of his job and situation.

There’s a point where he has to talk to Iris’ mother relating to her disappearance, and he tries to flirt and make plans with her – whilst her daughter is still missing, and he is the main detective assigned to her case! He’s punished for his advances in this specific scenario with a joke, ending where Iris’ mother gets rightfully upset with him, but this is one of many cases in the game where Date makes tone-deaf jokes similar to this. He is not criticized for it any more than Aiba scolding him and changing the subject, just for this to happen again, again…and again. 

If you haven’t played the previous AI: The Somnium Files games before this one, I would definitely recommend playing the other installments instead if you are looking for a game with a good story. The previous games have similar issues with character writing, but they aren’t as noticeable as they are in this game as there is a lot more focus on differing characters and perspectives. This is especially the case in Nirvana Initiative, where instead of Date as a protagonist, there is a shifting perspective between an older version of Mizuki and a new character named Ryuki. I enjoyed both of these characters as protagonists a lot more than Date as they know when to take things seriously whilst not being boring or overly rational.

 

Overall Experience/Likes and Dislikes

Overall, whilst I enjoyed No Sleep for Kaname Date- From AI: THE SOMNIUM FILES’s puzzles and gameplay, it falters drastically in its story content where it didn’t in previous games. If you are looking for a good mystery to sink your teeth into, you will definitely enjoy the Investigations, Somniums, and Escape Rooms presented in this game. However, if you are a returning fan or a new player looking to get into the series, whilst it is plausible to start with No Sleep for Kaname Date, I would not recommend it as a long-time fan of the series.

The previous games do a much better job of providing engaging characters and dialogue with more likeable protagonists than Date, whilst still maintaining the intriguing puzzles even with the lack of Escape Rooms through the Somniums and short puzzle sequences. With how No Sleep for Kaname Date failed to live up to the previous installments, maybe there should be some sleep for Kaname Date after all.
