Team Meat has provided the first clip from its upcoming catlady sim Mew-Genics. In a turn that can be described as, "very internet" if you have no paternal instincts towards the English language, the first clip is not a teaser trailer, but an animated gif (below). Also, be sure to read Edmund McMillen's explanation of the process and how you can start to see the mechanics at work in this little miracle.
Such a smile on the glowing mother's face. And the babies just pop! out in a cloud of dust or possibly amniotic fluid. Probably the fluid!
Very excited for this game.
