## Gameplay

A reboot of the 2004 game Yume Nikki, Yume Nikki: Dream Diary is structurally similar to and borrows some environments from the original. It is an adventure horror game focused on atmosphere and exploration. Unlike its predecessor, Dream Diary is rendered in 3D and includes areas with puzzles and platforming. Some sections are seen from overhead and some have a 2.5D perspective. The player controls a hikikomori named Madotsuki, who is seen waking from a dream at the start of the game. In Madotsuki's apartment, which can not be exited while she is awake, there is a game console the player can use to play a minigame and a dream diary that keeps track of the player's progress and collectibles.
The player can make Madotsuki sleep, which transports them inside her dreams to a room with eight doors, six that lead to new worlds, one that leads back to the real world, and one that can only be opened after the six worlds are finished. Inside these worlds, the player can collect items called Effects, which can help the player progress or unlock secrets. Throughout the game Madotsuki, who cannot fight, can encounter creatures, some of whom are hostile, and some of whom serve as obstacles the player must move. Each world has loosely-defined goals and ends with a cutscene, after which Madotsuki wakes up again. The player can also force Madotsuki to wake up at any time.
Dream Diary has a minimal plot, although some cutscenes contain story elements, and the game has two endings. The first requires the player to complete all six dream worlds to open a seventh door, which leads to a platforming sequence in which Madotsuki is chased. If the player escapes to Madotsuki's apartment, a cutscene shows her waking up, looking out from the balcony, and then leaving her apartment. The second ending further requires the player to collect a special item from each world after completing the game. After collecting all of them, the player can access a spaceship, where Madotsuki can play a song with a character named Seccom Masada. After playing the song, he will open a room with a bed in which Madotsuki falls asleep.

Yume Nikki: Dream Diary received a score of 51/100 on review aggregate site Metacritic, indicating "mixed or average reviews". Some critics compared the game with its predecessor—Rock Paper Shotgun's Adam Smith felt that Dream Diary had lost the "mysterious horror and charm" of the original game and called it "fan-disservice", and Adventure Gamers' Kevin Lynn said it introduced adventure platformer tropes while discarding the distinct, open-ended design of Yume Nikki. Tais Carvalho of TechTudo thought the introduction of more traditional gameplay elements had positive and negative effects, and that it made the game more accessible than the original to a general audience. However, Lynn said the game's new 3D visuals were a faithful translation of the original 2D textures, and Azario Lopez of DualShockers said that Dream Diary was a "decent attempt" at a reboot.
The game's presentation was generally well received by critics, with Carvalho and Hardcore Gamer's Chris Shive calling the visuals one of the best aspects of the game. Rubén Martínez of MeriStation noted that they did not think the game looked ugly, but called its visual style one of its worst aspects because they felt the pixel art style of the original was the source of a lot of its mystery. Reception to the world design was mixed. Smith compared the re-imagined designs to "bootleg DVD covers". Lopez said the world was dark and captivating, and he and Shive complimented the creature designs. Shive felt they were unsettling and captured the "chaotic and random" feel of dreams, but criticized them for being too linear. Lopez and Lynn both praised the game's atmosphere, with Lopez calling it a "decent surreal experience". The game's music was received positively; Lynn identified it as a strong point, helping contribute to a "lonely, haunting tone", and Carvalho, Martínez, and Lopez thought it was one of the game's best aspects, helping enhance the game's horror and atmosphere.
The gameplay was generally criticized. Smith said it was clunky and confusing at points, and Lopez said the controls were somewhat unresponsive at times, also mentioning he encountered a number of glitches while playing, which Martínez and Carvalho also criticized. Lynn found the controls mostly responsive, but criticized one section of 3D platforming for its camera and physics. Shive thought that, despite the interesting premise and strong visuals, the game was overall not enjoyable to play, citing linear world layouts and weak puzzles as contributing factors. Lynn also added that, despite the game having a good variety of worlds, they lost their impact due to excessive backtracking and the game's animations became "tiresome".
