StudioMDHR’s Cuphead is a resounding success, having sold over one million units in just two weeks. Making this milestone doubly impressive is that the game is exclusive to Microsoft’s platforms.

“We never could have dreamed of the reception we’ve received from our amazing fans,” a post credited to StudioMHR’s Chad and Jared Moldenhauer reads. “Today, we wanted to take a moment to thank each and every one of you for your support and we’re excited to share that Cuphead has gone platinum with over 1 million units sold.”

Cuphead is a visual feast, but it’s also somewhat controversial. The game was originally supposed to be released in 2016 and was in development hell for over two years, and received Microsoft funding to finish. Worse, the delivered game is simply too difficult for most gamers, and is a non-starter for casual gamers. My bet is that most of those one million sold games will never be finished. Hopefully, they’ll fix that.

Difficulties aside, I’ve been impressed by how easily that complaint has been cast aside by reviewers, all of whom seem to just love this game. Clearly, whatever StudioMHR did worked: You can’t argue with the sales figure. Especially for a game that is stuck on Windows (Steam, Windows Store) and Xbox One only.
