# Big Walk’s 10 lines of LLM-assisted code split the Independent Games Festival jury

*19 of 50-plus IGF jurors refuse to vote for any game using generative AI; House House says its fix was under 0.1% of the code*

## In brief

- House House disclosed that LLMs helped fix a Unity shadow bug in Big Walk, well under 0.1% of its code
- 19 of 50-plus IGF Awards jurors pledged not to vote for any game using generative AI in any capacity
- Valve’s Steam disclosure form covers AI-generated content but not coding ‘efficiency gains’
- The separate Indie Game Awards rescinded Clair Obscur: Expedition 33’s awards last year over AI textures
- Big Walk drew 400-plus negative Steam reviews but remains ‘Very Positive’ overall

Ten lines of code, from a codebase where those lines make up well under 0.1% of the total. More than 400 negative Steam reviews in a few days. Nineteen jurors out of a 50-plus-member awards jury refusing, in writing, to vote for any game that uses generative AI in any capacity. That is the arithmetic around Big Walk, House House’s co-operative puzzle exploration game, after the studio publicly and belatedly disclosed that it had used an AI chatbot to fix a bug, [as Kyle Orland reported at Ars Technica](https://arstechnica.com/gaming/2026/11/big-walk-used-ai-to-fix-a-bug-now-the-indie-gaming-world-is-having-a-reckoning/).

## The bug

The mechanism is specific. Near the end of development, Big Walk hit a Unity engine bug that produced shadows of ‘infinite length’ and slowed the game in some situations. House House says it consulted a Unity engineer, who determined a fix ‘wasn’t possible,’ and then asked an LLM chatbot, which suggested one. The developers ‘had to modify it extensively’ into the 10 lines that shipped. In the studio’s telling, published to Aftermath and then the game’s FAQ, ‘LLMs were used sparingly’ late in development ‘to help work through some difficult technical challenges and bugs.’ One caveat worth keeping: at least one social media user says the shadow bug was fixable — with significant human effort.

The disclosure chain is the second mechanism. When Big Walk shipped on Steam earlier this year, House House said nothing, because Valve ‘does not request disclosure of code or chatbot usage.’ Valve’s AI disclosure form for developers asks about AI-generated content and explicitly not ‘efficiency gains’ from ‘modern game development environments \[that\] have AI powered tools built into them.’ The Independent Games Festival Awards draw the line elsewhere, so House House mentioned the AI-assisted fix when submitting the game for awards consideration. The statement went public this week — after months of private jury discussion — because, the studio said, ‘it has become a matter of public interest.’

> We support the work of those who are trying to limit the harm generative AI is doing to videogames and our world, and apologize that Big Walk’s LLM usage may not meet their standards.

## The jury

The fight broke into public view on Monday, when 19 members of the IGF Awards jury released a signed statement ‘declining to vote for any game that uses generative AI in any capacity.’ Noting a significant increase in the number of submitted games developed with generative AI tools, they cited ecological, economic, psychological and labor harms, called adoption of the tools ‘not a foregone conclusion in our industry,’ and urged the festival to ‘adopt a strong anti-AI policy for future years that disallows games containing any AI-generated work.’ The statement named no game; by Tuesday morning, Big Walk was the central example anyway.

For some jurors the disclosure landed on real attachment. Austin Walker wrote that Big Walk was ‘an achievement,’ ‘remarkable’ and ‘beautiful,’ with puzzles that ‘capture a range of play that is largely abandoned by the digital form.’ Damon Reece called it ‘seriously special to me’ and described ‘a profound and powerful emotional reaction to being in a space that felt like home.’ Both concluded that even minimal AI use overrides that respect for awards purposes. ‘We have our hands on the lever here,’ Reece wrote. ‘This is pain that has to happen to try and steer our culture away from this. ... To do otherwise is rank cowardice.’

There is precedent. Last year the Indie Game Awards — a body entirely separate from the IGF Awards — rescinded awards for Clair Obscur: Expedition 33 after its developers admitted some in-game textures were made with AI tools; the textures were later patched out. ‘The Indie Game Awards have a hard stance on the use of gen AI throughout the nomination process and during the ceremony itself,’ the organization said then.

## Where the line goes

Not every juror accepts the one-line-is-disqualifying rule. Liz Ryerson wrote that House House’s use was not personally disqualifying for her and that ‘the fact that many acted like there aren’t any levels to this and it’s all the same is bothersome to me.’ ‘To feel like someone gets punished a lot more for transparency about a smaller level of fuckup vs. just not even attempting to be honest or transparent at all is what bothers me,’ she added. Steam Hype writer Dominic Tarason rejected the idea that the studio must be ‘memory-holed’ for touching ‘the Forbidden Device,’ calling Big Walk ‘very mildly compromised art’ that remains ‘absolutely, unquestionably art and very human.’ ‘They spent years on that work of art,’ he wrote. ‘They asked a chatbot for two minutes how to fix a bug. That’s a “That’s lame, don’t do that again” failing.’

Two middle positions are worth stating precisely. AI researcher Mike Cook argued the bug fix made development at least a bit less human than it could have been: ‘House House aren’t laying off developers to replace them with Claude ... but we can also clearly see how their actions are part of the same problem.’ Game developer and professor Brendan Keogh argued the opposite edge: ‘an extreme zero tolerance of any \[generative AI\] is ultimately counterproductive now,’ punishing developers honest enough to disclose ‘their glorified Google search’ and ‘encouraging those using it to actually steal labor to hide that use.’ For the absolutist side, narrative designer Hannah Nicklin wrote that ‘zero tolerance is a viable political position’: ‘You use politics against systems, for people you affect change through connection and understanding.’

The two disclosure regimes now point in opposite directions. Steam’s form treats AI-assisted coding as an efficiency gain not worth asking about; 19 IGF jurors want one line of it to disqualify a game entirely, while Steam’s anti-review-bomb tooling has so far kept Big Walk at ‘Very Positive’ despite the 400-plus negative reviews. Meanwhile engine vendors keep building AI tools into the development environment itself, which makes ‘untouched by AI’ a shrinking category — if the use is disclosed at all. The decision to watch is the IGF’s policy for next year’s awards, and the behavior it prices in: whether developers, having watched what ten lines cost House House, conclude that disclosure is the expensive option.
