A New Frontier of Risk for Indie Developers

Digital Sun Games, the studio known for Moonlighter and Cataclismo, has officially canceled its plans for a wide-scale public playtest of its upcoming "tower defensevania" roguelike, ReVamp. The decision stems from growing concerns regarding the rapid evolution of artificial intelligence models, specifically Anthropic's Claude Opus 5.5, which the studio fears is fueling a surge in automated game cloning and code decompilation.

While the threat of imitation has always existed in the industry, the speed at which AI tools can now analyze, reproduce, and iterate on original code has created an unprecedented landscape. Digital Sun Games is not alone in these anxieties, as other studios have begun reconsidering their public outreach strategies to protect their intellectual property.


Shifting Strategies for Security

Israel Mallén, the marketing manager at Digital Sun Games, explained that the team has moved its playtesting efforts to a private Discord environment. This shift allows for stricter oversight, including the use of Non-Disclosure Agreements (NDAs) and manual vetting of participants.

"Moving to Discord is really about control," Mallén noted. "We can see their activity on our server, and we can answer questions live as they play. On Steam, there's no way to vet individual users or tell an active player... from an account that was just created for the occasion."

This transition, however, comes at a cost. The studio must sacrifice the massive reach and feedback potential that a public Steam playtest would have provided, ultimately impacting the game's visibility and marketing reach ahead of its anticipated March 2027 release.


The Call for Platform Intervention

Reflecting on the state of the industry, the team expressed deep frustration with the current environment. "We've been making games for a decade, and we'd never felt this kind of worry about sharing our games with the community before," Mallén said.

«If you can’t show your game to the world without fearing it’ll be cloned, something’s broken.»

The studio believes that major storefronts, such as Valve's Steam, are in the best position to implement safeguards. Suggested improvements include:

  • Enhanced vetting tools for playtesters, based on account age, playtime, and review history.
  • Stricter protection mechanisms for original builds submitted to the platform.

The Future of Public Playtests

Looking ahead, Digital Sun Games warns that if industry-wide protections are not established, the culture of game development could shift negatively. Developers may increasingly avoid public testing until the final moments before a launch, transforming what was once a collaborative feedback mechanism into a mere marketing tool.

"Unless measures are taken, public playtests and demos far from launch will feel risky," the studio cautioned. "If that fear spreads and protections don't arrive, developers will hold back. We'll see fewer public playtests and demos."
