This guy's too humble. He's Matheus Valadares, and he's the creator of Agar.io [1]. This is the game that pretty much started the ".io game" genre [2].

[2]: "Around 2015 a multiplayer game, Agar.io, spawned many other games with a similar playstyle and .io domain". See https://en.wikipedia.org/wiki/.io

Similar to John Carmack coming into a thread and saying he’s worked on a game or two.

Love agar.io and HN for this

That's cool, I love io games. Which ones?

Most well known one is probably agar.io. I made a couple of other ones like diep.io, and most recently digdig.io
