What the developer says
Yes, this game has been built with AI. As a software engineer for over 15 years, I wanted to see how far I could push AI to bring my idea to life. I built the initial prototype myself, but have used AI extensively to turn the prototype into a fully functional game that looks and feels the way I imagined. This is still months of work with over 50 hours of playtesting to bring it to life. AI has come a long way, and game development is evolving fast. This game would never have left the prototype stage without it. Please consider giving it a chance.

| AI judgment deepseek-flash | Major AI · mixed signals, medium confidenceReasoningThe disclosure states AI was used extensively to build the game beyond the initial prototype. That suggests AI touches several major asset types, not just minor details. The developer reports months of work and 50+ hours of playtesting, so effort is not clearly low. Against: The developer built the prototype themselves and reports substantial playtesting; the game is unreleased with no reviews, so the exact share of AI-made assets is unknown. |
