Digital Sun officially delayed the public Steam playtest for its upcoming tower-defense action title ReVamp this week, citing urgent risks that aggressive AI scraping tools could reverse-engineer its proprietary mechanics and clone the game ahead of launch. According to verified reports from Eurogamer, the Spanish studio behind Moonlighter and Cataclismo voiced deep frustration over bad actors publishing automated knockoffs of unreleased indie projects onto mobile storefronts. Digital Sun explained that open playtests expose unprotected core gameplay loops, allowing algorithmic scrapers to replicate unit pathfinding, level pacing, and hybrid combat architectures within weeks. The developer will pivot toward smaller, private closed-door testing cohorts under strict access controls rather than a completely open public Steam demo. This proactive posture follows widespread publisher anxiety regarding intellectual property theft across PC ecosystems, mirroring broader regulatory moves across Europe such as the [PEGI Loot Box Age Rating Raised to 16 Across EU [Confirmed]](/news/pegi-loot-box-age-rating-16) initiative. By locking public builds down, Digital Sun protects years of custom development from being cannibalized prior to its retail debut.
