Three months after its launch, indie hit Untitled Goose Game from developer House House has gone platinum.

The milestone was revealed on Twitter (below) by Cabel Sasser, the co-founder of publisher Panic Inc, who said that the game had sold one million copies towards the end of 2019.

This followed Untitled Goose Game's release on PlayStation 4 and Xbox One on December 17th, which came in the wake of its PC and Nintendo Switch debut on September 20th.

"The reaction was beyond anything we could have imagined. The fan art, the writing, yes the memes, protest signs, Chrissy Teigen, Muppets?! It feels once-in-a-lifetime," Sasser said on Twitter.

"We hope we brought some joy into your life, because you brought so much into ours.

"And we'll never forget it."

The game launched after becoming a social media sensation thanks to some rather hilarious gifs of the game that started to circulate.

Last year, programmer Nico Disseldorp said that while the game became successful and gained a great deal of traction thanks to social media, developer House House didn't think a huge amount about this when actually making the game.

It seems impossible, but last week, three months after launch, Untitled Goose Game passed one million copies sold.

From the bottom of our hearts: thank you for playing our videogame.
