Mewgenics co-creator Edmund McMillen says there are details about the cat breeding tactical roguelike that nobody has found yet.
Over two months since release, Mewgenics is still my choice for the best game of the year so far, and it's going to take something extremely special to unseat it from its cat turd-covered podium. Personally, I've put about 120 hours into the game and still feel like I won't be seeing the end of it for a while yet, but given how popular it's been and how many hours some have put into the game, everything about it must be out there now… right?
It’s crazy that at this point there are still aspects of mewgenics that people haven’t figured out yet. :)April 23, 2026
McMillen took to Twitter to marvel, "It’s crazy that at this point there are still aspects of Mewgenics that people haven’t figured out yet," and when pressed whether he meant from the lore or gameplay front, the game director explained, "Both, but more lore than gameplay."
Of course, some will undoubtedly take this as a challenge to find out anything and everything about the game. McMillen is no stranger to elaborate secrets; just look at some of the bizarre unlock requirements in his other famous roguelike, The Binding of Isaac. Namely, The Forgotten, which required an elaborate multi-step quest that took place across the whole game, allowing you to unlock the character during the final area of your run.
Of course, this also invites players to datamine the game to find out things that were supposed to be hidden, which is exactly what happened in The Binding of Isaac Rebirth, much to McMillen's dismay.
