A groundbreaking combination of cat breeding, tactical RPG, and roguelike.
Master Edmund McMillen’s ambitious work, completed after two hiatuses
A choice that didn’t compromise with reality paid off, earning it the highest-rated film of 2026.
Officially released on Steam on February 10, 2026, the indie game “Mewgenics” has received overwhelming acclaim from both critics and users, emerging as one of the best-reviewed games of 2026. Immediately following its release, the game earned a “Must-Play” rating, garnering an average Top Critic score of 90 and a 94% recommendation rate on OpenCritic.
Mewgenics, first announced in 2012, underwent a complete redesign and development halt, finally making its debut after a staggering 14 years. Despite facing numerous setbacks during its lengthy development period, it ultimately earned praise as “an indie game that proved worth the wait.”
Indie game giants join hands again.
The people leading the development of Mewgenics are two developers familiar to indie game fans.
Edmund McMillen, who rewrote the history of indie games with Super Meat Boy (2010) and The Binding of Isaac (2011), is a developer and artist born in California, USA in 1980. He He began his career creating games on Newgrounds, an indie creative community where people share Flash-based games, animations, and music, and has established a unique presence with his bizarre and intense art style.
Co-developer Tyler Glaiel is also a legendary figure in the indie scene. Born in 1990, he has been a fixture on Newgrounds since his teens, and in 2008, he won the Indiecade Gameplay Innovation Award and the IGF Audio Award for Closure. In 2016, he was named to Forbes’ “30 Under 30” list for games.
The two first collaborated on Aether in 2008, and their synergy was further demonstrated in 2017 with the joint development of The End Is Nigh. Glaiel’s proprietary game engine, in particular, played a key role in the development of Mewgenics, as it allowed for efficient use of Flash-based assets.
After numerous setbacks, it was completed after a tumultuous 14-year journey.
Mewgenics was first unveiled in October 2012 by McMillen, then of Team Meat. Initially conceived as a turn-based strategy game inspired by The Sims, Pokémon, Animal Crossing, and Tamagotchis, it was initially scheduled for a public demo at PAX East in 2014, but development was halted in August of that year due to concerns about the direction of the gameplay.
In 2016, McMillen officially canceled development on Mewgenics and left Team Meat to focus on The Legend of Bum-bo. He stated that he wanted to pursue new intellectual property, but his co-founder wanted to focus on the Meat Boy franchise.
The turning point came in 2018. McMillen reclaimed the rights to Mewgenics from Team Meat and resumed the project with Tyler Glaiel. After several prototypes, the current turn-based tactical RPG structure was finalized in early 2020.
“It would have been much easier to make The Binding of Isaac 2,” McMillen explained, “but we chose a more difficult, more novel challenge.”
From cat breeding to breeding and tactical combat
The fun of Mewgenics stems from its unique game structure, where cat breeding and adventure are organically linked. Players breed cats, send them on one-time adventures, and use surviving cats for breeding. Once a cat completes an adventure, it retires and no longer participates in battle.
Cats that survive their adventures form relationships with one another, leaving behind offspring with a mix of traits, mutations, strengths, and weaknesses. The genetic system creates virtually endless combinations, such as a tank inheriting a mage’s teleportation ability, or a healer transforming into a damage dealer with attack-focused mutations.
As the game progresses, you can learn about your cat’s disposition, mood, sexual orientation, relationship preferences, and even inbreeding status through the NPC ‘Tink’, and these settings act as strategic and narrative choices that go beyond simple numbers.
Tactical combat dominated by environment and logic
Battles take place on a randomly generated grid, and all enemies must be defeated to advance to the next stage. Environmental factors such as weather, terrain, and vegetation directly impact the outcome of battles. Realistic interactions are naturally reflected, such as a cat on fire crossing a field of grass causing flames to spread.
If a cat falls, it won’t die immediately, but it could suffer permanent damage, such as brain damage. If the cat dies completely, any items it was holding will be permanently lost, so all battles must be fought with caution.
A vast amount of content with no end in sight
The game features over 1,000 unique abilities and over 900 items. Enemies include virtually every type you’ve seen in games and movies, including giant monsters, cultists, aliens, mad scientists, dinosaurs, and fascist robots.
Developer McMillen described Mewgenics as “one of the biggest tactical RPGs ever made,” adding that “the average gamer will need over 200 hours to finish the game, and over 500 hours to achieve 100% completion.”
Critical acclaim: “Time disappears”
Reviews from overseas media outlets are consistently favorable.
GamesRadar+ praised the game’s “design that makes even randomness part of the strategy,” while GameSpot praised its “boundless variety and absurd humor.” The Guardian noted that “after 60 hours of play, I haven’t even seen a third of it,” and PC Gamer also noted that new content continues to appear even after 100 hours.
McMillen confirmed Mewgenics’ DLC development in a post-launch interview and revealed that they are looking for a publisher for a console release, with the next-generation Nintendo Switch 2 being mentioned as a potential platform.
14 years of waiting, the culmination of indie game obsession.
Completed after two development hiatuses and a complete genre redesign, Mewgenics is a symbol of the tenacity and experimental spirit of indie game development.
Edmund McMillen and Tyler Glaiel could have chosen the easy way out. As the developers put it, “If we had made The Binding of Isaac 2, we would have had 20 million wishlists immediately after its release.” Following a proven formula for success would have been a much safer bet. Instead of repeating familiar successes, however, they ventured into the uncharted waters of the strategy RPG. The result: a 90-point OpenCritic score and a 94% recommendation rating, making it the highest-rated game of 2026.
With over 500 hours of content, over 1,000 abilities, and nearly infinite genetic combinations, this isn’t just a show of scale. It’s a design that demands “exploration” rather than “completion,” challenging the market’s accustomed focus on rapid consumption. While Mewgenics may be cloaked in the guise of cat breeding, its essence is closer to a complex strategy simulation genre where choices and consequences accumulate.
Ultimately, the question Mewgenics poses is clear: can indie games still take risks, and can those risks be rewarded? This game offers one answer to that question: that, at least in the current indie game landscape, uncompromising choices can still yield meaningful results.
