Pixel Galaxy is an instrumental electronic track by Japanese producer Snail's House (Keitaro Ujiie), an artist well known in the doujin and rhythm game communities for his kawaii bass and chiptune-infused sound. Released at 150 BPM, the song pairs crisp synth melodies with a driving beat that evokes the retro-futuristic aesthetic its title suggests. The accompanying music video was created by Speedoru, adding a visual layer of pixel-art charm to the track. The song joined the maimai でらっくす PRiSM PLUS lineup on August 1st, 2025 as part of the GAME & VARIETY category, with its Asian version release following on January 9th, 2026. Outside of maimai, Pixel Galaxy appears in several other rhythm games including Muse Dash, WACCA, and Taiko no Tatsujin, giving it a presence across multiple arcade and mobile music-game platforms. In maimai, the Expert chart was designed by サファ太 (Safata) and the Master chart by じゃこレモン (Jako lemon), with the Master chart carrying a 13.1 difficulty constant and 721 total notes, a substantial layout that tests players with its dense patterning and 60 Break notes.
