Dev lets Claude autonomously build Dark Pattern, a Balatro x Diablo II mashup
AccountlKiller · reddit · 2026-11-16
A Reddit developer used Claude (Fable 5.2) in a near-fully autonomous workflow to build Dark Pattern, a card roguelike mashing up Balatro and Diablo II, now playable online.
- Reverse workflow: instead of writing detailed prompts, he let Claude interview him via rounds of 10+5+3 questions, then handed over full control and went to bed
- He provided an OpenRouter key with $7 left: generate images first, voiceovers second, draw SVG yourself when money runs out — the broke first version came out as a "SaaS dashboard," which Claude dutifully logged in its dev log
- The game engine was solid; most rework went into UI redesign and stripping decorative excess
- Human playtesting was useless (three friends called it impossible, boring-easy, and just right), so balancing was done with 600 bots across tens of thousands of simulated games
- Final result: "looks like Balatro, feels like Diablo II, steals ideas from Path of Exile"; he burned three usage resets in a weekend and brought in Opus 5.5 for final code review
