In an interview with IGN, developers Edmund McMillen and Tyler Glaiel confirmed that their tactical roguelike about cats, Mewgenics, exceeded all sales expectations in less than a day after release. According to the authors, the game took only three hours to fully recoup the development costs.
The launch of Mewgenics was successful: initial sales exceeded the figures for any add-on for The Binding of Isaac: Rebirth. In just 5.5 hours, about 152,000 copies were sold. At the same time, the online presence continues to grow — the peak number of simultaneous players is already approaching 66,000, and, as the developers note, this figure will surely be even higher on the weekend.
