US indie developer Galvanic Games is closing its doors. 

In a post on Twitter, studio president and founder Patrick Morgan announced that it was shutting down due to sales of its most recent game, Wizard with a Gun, not selling enough to allow the company to stay in business.

"Despite the promising start of Wizard with a Gun, sales are not strong enough to sustain our studio," Morgan wrote. 

"The last year has been particularly tough for games. While we had numerous encouraging conversations at DICE and GDC, the process of signing new projects, even in a good year, takes longer than the runway we had left."

The studio continued: "There is a certain bittersweetness to knowing that we accomplished all the things we set out to do when we founded Galvanic in 2015. From launching unique, weird, and interesting games to collaborating with some of my favourite people in the industry all while building a tight-knit, productive team focused on a healthy and creative culture.

However, it is incredibly difficult to see our team facing the uncertainty of the current job market. I may never get over the irony of spending a decade building my ideal team, only for it to end after our most productive year. The dedication, creativity, and hard work of every person on our team have been nothing short of extraordinary."

Galvanic was founded back in 2015.
