The music received mostly positive reviews from critics. Aurora Amidon of
Paste called it as "groovy, video game-like score". Alex Maidy of
JoBlo.com wrote "Lorne Balfe's music is rooted in the MIDI sounds of classic Nintendo and arcade video games, while the 8-bit graphic transitions used through the movie lend a fun vibe. The period-appropriate music also adds a nice element." Tim Grierson of
Screen International wrote "Baird leans into the bizarreness of this tale’s stranger-than-fiction premise while affectionately mocking the period’s dated tech and pop songs. The playfulness extends to establishing shots that are presented as 8-bit graphics, while Lorne Balfe’s score mimics the cheesy-futuristic keyboard style of ‘80s sci-fi soundtracks." Dan Jolin of
Empire called it as "a predictably catchy electro score". Matt Donato of
IGN wrote "Lorne Balfe’s original score, meanwhile, is an early frontrunner for my favorite of the year; the familiar notes of Tetris’ stage background music bounce around Balfe’s compositions like smooth Synthwave jams or quirky chip-tune remixes." Catie McCarthy of
Screen Speck wrote "composer Lorne Balfe elevates the already-iconic Tetris theme into a dramatic spectacle" and also commented "The needle-drops are similarly fantastic, too, with classics like “The Final Countdown” and “Holding Out for a Hero” playing in multiple languages to thematic effect." Patrick Cremona of
Radio Times wrote "The electronic score by Lorne Balfe also makes excellent use of the iconic Tetris theme music, while there is a soundtrack that includes a number of enjoyable if fairly obvious era-appropriate needle drops. It all adds up to something that might not quite live up to the film's billing as a Cold War–era thriller "on steroids", but nonetheless manages to tell an intriguing story in an engaging and entertaining manner." == Score album ==
