The tool is a paid offering, and the developer shared it on Hacker News to solicit improvement ideas.", "body_md": "Hey everyone! Wanted to show off a little side project I've been working on. A lot of people have been using AI to one-shot games, but they're often quite buggy - glitchy graphics, collisions aren't setup, or regressions in earlier levels. With an AI playtester in the loop, I've been able to one-shot games like Candy Crush or Crossy Road that would previously have bugs like cut-off UIs or stuck retries.\n\nThe way it works basically goes like this:\n\n1/ The playtester starts by reading the code to understand what its parent AI is asking it to play, and to decide what breakpoints, hooks and logging to add 2/ The playtester sets up the scene with the needed environment 3/ The playtester sends a sequence of inputs, then pauses the game 4/ The playtester then uses a vision model to understand the scene, queries the hooks it initially set up, and reads the logs to decide what to do next\n\nAfter doing a few input loops, it then determines if the game is working, the game is broken, or if the test failed.\n\nIt is a paid offering so I'm not expecting anyone to try it out, but I wanted to share it nonetheless ^^. Lmk if you have other ideas on how you think it can be improved\n\nComments URL: [https://news.ycombinator.com/item?id=49475316](https://news.ycombinator.com/item?id=49475316)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-ai-game-playtester", "canonical_source": "https://ziva.sh/full-game-tester", "published_at": "2026-08-28 07:06:59+00:00", "updated_at": "2026-08-28 07:18:33.137247+00:00", "lang": "en", "topics": ["ai-tools", "generative-ai", "computer-vision"], "entities": ["Candy Crush", "Crossy Road", "Hacker News"], "alternates": {"html": "https://wpnews.pro/news/show-hn-ai-game-playtester", "markdown": "https://wpnews.pro/news/show-hn-ai-game-playtester.md", "text": "https://wpnews.pro/news/show-hn-ai-game-playtester.txt", "jsonld": "https://wpnews.pro/news/show-hn-ai-game-playtester.jsonld"}}
