Note written 2026-08-25; the live figures above take precedence over any numbers in it.

A 1799 Spanish monastery stealth-puzzle adventure with hand-drawn art, dual campaigns, and high mechanical difficulty that punishes mistakes severely.

Stone of Madness has shipped 6,240 lifetime units at $29.99 with 79% positive sentiment and strong retention (100% still-playing), yet generates only $973/mo residual revenue and sees minimal dev communication (13.8 months since last post). The title sits in a viable niche: hardcore puzzle-stealth with distinctive visuals and international appeal (44 Spanish, 28 Simplified Chinese, 13 Korean reviews). However, zero discount promotions in 12 months, no recent build updates, and a persistent friction point (lack of manual saves) suggest either deliberate design philosophy or post-launch resource constraints. For a publisher or product team, this represents either a quiet earner deserving light marketing refresh, or a candidate for targeted QoL patches that could unlock a larger audience without abandoning the core vision. Most realistic play: publishing.

• Risk: Mid-game save-state corruption reported in player feedback; checkpoint-only design polarizes audience and may cap addressable market.
• Risk: Hardcore puzzle-stealth is a small, self-selected segment; 6/month peak 30-day players and zero promotional activity in 12 months suggest limited organic discovery momentum.
• Risk: 13.8 months since developer communication and 10.5 months since build update raise questions about ongoing support capacity and post-launch roadmap commitment.
