Overview
Dopamine Software is a Japanese video game circle (dōjin soft developer) that publishes its own titles through its official website at soft.dpmn.net.

Its best-known works include puncTure (released at Comiket 64 in 2003), Acmeholic (Comiket 70, 2006), and Cattle Couple (Comiket 76, 2009). The homepage presents these titles with event pricing and download pricing, indicating a direct-to-consumer distribution model typical of Japanese dōjin circles. The circle's output is small and self-published, with each title tied to a specific Comiket event. puncTure is noted as having been an entry in the "God Game" (ゴッドゲーム) contest, and the homepage describes it as a game that can be enjoyed by a wide range of players, from beginners to experienced players. Acmeholic is described as a bonus (おまけ) title with a music-focused or music-attached element. Cattle Couple is described as a 100-yen eroge (adult game) with a low price point. Dopamine Software operates primarily in the Japanese dōjin market, selling physical copies at events such as Comiket and offering downloads through its website. Wikidata classifies it simply as a Japanese video game company. The circle does not appear to have a large corporate structure, and no parent company, founder, or headquarters information is available in the supplied evidence. Its identity is tied to its website and its small catalogue of self-published games.
