Mewgenics has sold over one million units just seven weeks into 2026, surpassing Hades 2 in peak player count on Steam. Co-creator Tyler Glaiel expressed surprise at the game's success, noting it exceeded pre-launch wishlist numbers, which rose from approximately 400,000 to around 600,000 before launch. The game's player demographics include the USA, China, Germany, the UK, Canada, France, Russia, Australia, Spain, and Poland, prompting considerations for adding translations in Simplified Chinese, Japanese, Korean, and Russian.
