First-person PC and PlayStation 4 adventure game Firewatch sold around 500,000 copies in its first month, publisher Panic announced in a blog post . Priced at $20, the game has now brought in around $10 million in revenue.

Panic also shared that, after just one day, the publisher recouped its investment in the project. The publisher said the way it measures success may be different than developer Campo Santo, but Panic is happy to report that Firewatch has been a success.

“Of course we wanted to make the best possible game we could, but we also had made an investment we really hoped to recoup,” Panic said. “How’d it go? Firewatch’s budget, while huge for us, was modest for a game of its quality and scope, but we made our investment back in about one day.”

Firewatch, released in February, was also the top-selling game of that month on PlayStation Network, outperforming AAA action game Far Cry Primal from Ubisoft.

“As an indie game, or heck, even as a ‘real’ game, ok fine but not as a Call of Duty or Star Wars game, Firewatch can be considered a sales success,” Panic said. “We’re so grateful. And relieved. But mostly grateful.”

Also in the blog post, Panic discussed Firewatch’s post-launch support, which so far has included a patch that improved performance on PS4. Looking ahead, players can expect even more updates.

“We’re not quite done. We’re still fixing bugs,” Panic said. “And we’re still working on ways to improve performance all across the board, including on PlayStation 4 and the Mac. There’s more to come.”

Panic also addressed Firewatch’s polarizing ending.

“Some people really loved Firewatch’s ending, others didn’t,” the publisher said. “Both opinions are completely valid. But we wanted to tell a ‘real-life’ story, and those often end quietly and sadly. We’re just grateful people played enough to have an opinion!”

Finally, Panic revealed that Firewatch players so far have uploaded 214,802 photos through the in-game camera that prints real-world photos.
