Indie developer Studio Thunderhorse is shutting down. 

The news came via Twitter, where the outfit said that it was closing its doors due to "a number of challenges and development hurdles".

Thunderhorse was founded by Simon Filip started life in 2015; that same year, the company made two mobile titles – Samurai Blitz and Raccoon Rascals – before moving into PC titles with 2021's Flynn: Son of Crimson, which it funded via Kickstarter. 

The project was funded by Humble Games; there's no indication whether that outfit's closure has anything to do with Thunderhorse shutting down. 

"After more than a decade of developing games and being part of this incredible community, we've had to make the difficult decision to close Studio Thunderhorse," the developer wrote. 

"It's been an amazing journey full of passion, creativity, and most of all, the chance to connect with all of you, which makes this decision all the more difficult.

"Despite our best efforts over the past months, we've encountered a number of challenges and development hurdles that have made it clear that stepping back is the right choice for the long-term health of the team and the studio.

"We are endlessly grateful for the support, love, and memories you've shared with us. Thank you for being part of our story, it's one we'll cherish forever."
