Alphabet

Wired called the game's premise "deceptively straightforward", stating that the Fantastic Arcade version's gameplay became "frantic" as the amount of characters they had to control increased and describing the game as "overwhelming insanity". They also recounted that even the 10-letter version was "simply beyond [their] capacity to handle." Paste, who found it "endearing", called it the third-best game from Fantastic Arcade 2016. While they described it as a "frantic typing mess" and remarked that they became "annoyed in harder levels," they concluded: "Alphabet has a great deal of style and charm, and is unique enough that it's hard to dissuade anyone from trying it at least once."

Announced in 2012, the game was originally developed and released as part of Experimental Game Pack 01, a collection of games released to Kickstarter backers of LA Game Space in 2013. The game was first made playable to the public at an event hosted by Juegos Rancheros on April 5, 2013, while the downloadable game pack released that September. In December 2013, Japanese magazine Dengeki offered skins for the PlayStation Vita themed around Alphabet and Tenya Wanya – another of Takahashi's games. The game was later re-released in an arcade format for the 2016 Fantastic Arcade, and when LA/GS ceased operation in 2018 the Windows version of the title was made freely available via The Internet Archive. From January 23 to July 14, 2019, Telfair Museums ran an exhibition at the Jepson Center entitled "Keita Takahashi: Zooming Out", featuring various elements of Takahashi's work including Alphabet. The game was presented at the installation with a custom controller table with large circular buttons for each letter.
