Critics Praise Mewgenics Ahead of Release

The long-awaited roguelike Mewgenics is finally launching on February 10 — and early reviews suggest that Edmund McMillen and Tyler Glaiel have delivered something special.

Currently sitting at 90/100 on OpenCritic (based on 19 reviews), Mewgenics is already being described as one of the most ambitious projects in McMillen’s career.

A Tactical Roguelike About Breeding Battle Cats

At its core, Mewgenics combines:

  • Tactical turn-based combat
  • Deep genetic breeding systems
  • Roguelike progression
  • Massive content variety

Players breed cats with unique traits and mutations, then command them in strategic battles filled with synergies and unpredictable outcomes.

According to critics, the game contains enough content to last hundreds of hours, with near-endless build combinations and procedural variation.

Review Highlights

Several outlets have delivered glowing praise:

  • TechRaptor (10/10) called Mewgenics the magnum opus of McMillen and Glaiel, highlighting its immense depth and addictive breeding mechanics.
  • VDGMS (9/10) compared it favorably to the best tactical strategy games, praising its complexity and replayability.
  • The Punished Backlog (8.8/10) emphasized how even after 30+ hours, the game still feels largely unexplored.
  • PCGamesN (8/10) applauded the strategic depth but criticized the game’s divisive humor and visual tone.

Not for Everyone

Despite its high scores, Mewgenics isn’t universally accessible.

Common criticisms include:

  • A steep difficulty curve
  • Dark, offbeat humor
  • McMillen’s distinctive (and sometimes grotesque) art style

The tone and presentation may not resonate with every player — but for fans of his previous work, it’s part of the appeal.

A Natural Evolution for McMillen

Mewgenics builds on the legacy of McMillen’s previous titles, including:

  • The Binding of Isaac
  • Super Meat Boy
  • The End Is Nigh

Like those games, Mewgenics blends mechanical depth with unsettling humor and strong identity.

Explosive Launch Sales

Just 36 hours after release, Mewgenics crossed an impressive commercial milestone — over 500,000 copies sold.

For a niche tactical roguelike with a highly distinctive visual style, this is a remarkable launch performance. The rapid sales surge suggests that strong reviews, Edmund McMillen’s reputation, and word-of-mouth momentum translated into immediate commercial success.

Combined with its 90 OpenCritic score, Mewgenics is shaping up not just as a critical darling, but as one of the most successful indie launches of the year.

Analysis: A Roguelike That Pushes the Genre Further

What makes Mewgenics stand out is not just its absurd premise, but its systemic depth.

While many roguelikes rely heavily on randomization, Mewgenics layers:

  • Genetic inheritance systems
  • Long-term progression
  • Tactical synergy planning

This gives it more strategic permanence than the average run-based game.

The 90 OpenCritic score signals something important: even after years in development, Mewgenics didn’t lose its edge.

If word of mouth holds strong after launch, it could become one of the defining indie roguelikes of the decade.
