Mike Bithell's indie hit Thomas Was Alone has now sold over one million copies.

Bithell himself tweeted the milestone with shock, ushering in a cacophony of congratulations from fans and well-wishers.

The game began life was a Flash-based browser in 2010. Two years later, it was released as a bigger game on PC and Macs in 2012. A year later, it hit the PlayStation 3 and PS Vita thanks to Bossa Studios and Curve Studios. It also showed up on Linux after being included in a Humble Bundle in May 2013.

Now, nearly four years since the first iteration was born as a free-to-play Flash game, the indie platformer has sold over one million copies across five different platforms.

You can grab Thomas Was Alone on Steam for PC, the PlayStation Store and on Xbox Live. Bithell recently corrected a tweet that claimed Thomas Was Alone was going to be available on GOG.com for free, but there are no plans to bring the game to GOG.com since they rejected it once before.
