A Nintendo Switch port was released worldwide in September 2017.

Gameplay
The core gameplay of Deemo is a score-based music video game. Each playable song features three main levels, namely Easy, Normal, Hard, each given a difficulty rating measured in a 'Level' scale. The levels were originally being ranged between 1 and 10, however the introduction of the Level 11 song Myosotis in the 2.0 version and the Level 12 song Marigold in the 3.0 version, marks the extension of the levels range, now being ranged from 1 to 12. A few selected songs also have an unlockable "Expert" difficulty which may have letters in place of the level number. The player can also customize the speed of the notes before starting a level, in a scale of 0.5 (slowest) to 9.5 (fastest). Songs can also be "autoplayed" (in the Chart Mode ), which plays the song automatically but disqualifies any scores and limiting tree growth.

In each level, a black line is affixed at the bottom of the screen, and horizontal bars known as "notes" approach the line at a perspective from background to foreground. The player must tap on the notes when they reach the bottom line in time with the music, resembling playing on a piano. Black notes require the player to tap each individually, while yellow notes allow the player to slide across in a chain. Black notes with a white interior are the same as normal black notes, only representing non-piano sounds, but otherwise the same gameplay-wise. Mine notes are the opposite: the player should not tap or slide the note when they reach the bottom line.

The player's performance is judged by the accuracy at which each note is hit, where a "Charming" hit is more accurate than a normal hit. "Charming" hits are subdivided into two types, "True Charming" and "Regular Charming", where "True Charming" means hitting exactly at the bottom line. Misses are also subdivided into three types, white, red, and no glow. At the end of each level, the game shows the player's overall performance in a result screen, providing the proportion of "Charming" hits, the longest chain of consecutive successful hits (Combo), and the overall accuracy in percentage form, with 100% denoting all hits are "Charming". The result screen will congratulate the player for hitting all notes successfully (Full Combo) or achieving 100% accuracy (All Charming). Hitting all notes with a "True Charming" is called 理論値.

The player's performance may also be judged by the "Energy", which starts at 100% in the beginning of the song. All types of hits (True Charming, Regular Charming, Normal) increase the Energy, white-glow Misses neither increase nor decrease the Energy, while red- and no-glow Misses decrease the Energy. The song is automatically failed when the Energy is empty at any time during the song. If there is a certain amount of Energy remaining at the end of the song, the song is cleared. One achievement in Deemo Reborn, called "I Miss You", requires a player to clear a song with all Misses. This means, a player should obtain as many white-glow Misses as possible while not obtaining any type of hits.

Playable songs
Deemo uses both instrumental and vocal music to accompany its rhythm game elements. The selection consists of works from composers from multiple regions including Taiwan, Japan, South Korea, and Hong Kong. Notable contributors include Earthbound Papas and guitarist Shinichi Kobayashi. Deemo also uses songs that were used in Cytus, another rhythm game by the same developer and songs from Alim's Role-playing game Brave Frontier for the game's collaboration event.

Plot
The game's plot centers around a little girl named Alice who falls from an open trapdoor in the sky and a mysterious black being named Deemo, who, to help the girl return to her own world, plays piano music so that a special tree sapling sprouting from the piano will grow. As the tree grows, various rooms of the structure open for Alice to explore. She also encounters a person wearing a white gown and mask, referred to as the "Masked Lady", who expresses annoyance towards Deemo and the girl trying to grow the tree.

When the tree stops growing at a height of 20 meters, Alice discovers a stairway through a painting in the side room and walks into it with Deemo. The stairway leads to a chamber with another piano covered in thick thorns. As Deemo plays that piano, large-scale tremors occur and the tree resumes growth.

The tree stops growing again at a final height of 50 meters, and a final room is unlocked. As the girl and Deemo enter the thorny room, the Masked Lady grabs hold of Alice and the two struggle. Deemo stops the Masked Lady with pats on her head, and proceeds into the room with Alice, leaving the Masked Lady behind.

The final room contains a piano and a hovering platform. Deemo plays more piano music which builds a stairway to reach the platform. When the stairway is complete, Deemo walks up to a platform with Alice and raises her onto it, then returns to the piano to play one final tune. The playable song ends with the message "Goodbye, my beloved sister, Alice.", suggesting the girl's name.

As the song finishes, Deemo is revealed to be a manifestation of Alice's elder brother Hans, and gradually disintegrates. A series of flashbacks reveals that the siblings were involved in a fatal traffic accident in which Hans sacrificed himself to save Alice. Alice bursts into tears as the platform rises towards the trapdoor and the Masked Lady removes her hood and mask, revealing her as another Alice (whose name was revealed to be Celia in The Last Recital) who wanted to prevent her from leaving so that they could be with Hans. As Deemo's world crumbles and he disappears, Alice wakes up in a hospital bed, attached to medical monitors. She removes them and rushes to the window to find that she has escaped Deemo's world, that she was in a coma the whole time, and that Hans died after the two of them were hit by a truck. Alice collapses into tears as nurses rush to her side to try and comfort her. After the credits, it is revealed that she takes up piano playing in his memory.

Release
Deemo was released on 13 November 2013, on the App Store, and 27 December 2013, on Google Play for Android devices. Formerly, the Android version is a free trial only allowing limited progress, the full version of which can be unlocked by an in-app purchase.

Deemo received generally positive critical reviews.
