Show HN: I built a game on my old phone without knowing what I was building

[kikkupico]

I'm calling this "Vibe Discovery" — distinct from vibe coding because I didn't know the requirements upfront. Started with "make something with the accelerometer" and discovered through 6 iterations that I wanted a WebGL marble game. The interesting part was the dev setup: Claude Code running in Termux on a Redmi Note 9 (4GB RAM). The same-device feedback loop — code, test accelerometer, react, iterate — made rapid discovery possible in a way that laptop-to-phone deployment wouldn't.

Why can't we just call it "play". That is what we used to call doing things without a purpose.

I wish people would disclose when they used an LLM to write for them. This comes across as so clearly written by ChatGPT (I don't know if it is) that it seriously devalues any potential insights contained within. At least if the author was honest, I'd be able to judge their writing accordingly.

There was a very specific purpose here - to build a web-based accelerometer game. If I were to compare this with playing, I would say this is more akin to playing with a special kind of clay that shape-shifts itself based on your instructions.

As for the LLM-generated writing - I've updated the blog post with a 'meta' section explaining how LLMs generated the post itself. I've shared the link to the specific section as a response to other comments with the same criticism - I don't want to link to the blog again here and risk looking like a spam bot.

I'm just vibe playing nowadays. Normal playing doesn't cut it anymore.

You posted the prompt to the game, care to post the prompt to the blog post? I don't care what an LLM thinks about how you built your game. I would like to know what you think, but I'm not going to try to salvage it from an LLM-generated blog post.

The blog post was written by Claude Code, reviewed by Gemini Pro, ChatGPT 5.2 Thinking, Kimi K2 Thinking, Deepseek Deep Thinking and me. Naturally, all the LLMs failed to judge that AI-generated writing is a turn-off for most readers. I failed to judge that too.

Quoting: “ What I’m describing is different. I’ll call it Vibe Discovery: you don’t know what you’re building. The requirements themselves are undefined. You’re not just discovering implementation - you’re discovering what the product should be.

The distinction matters:”

What is it with this pattern of phrases that screams LLM to me? Whenever I come upon this pattern I stop reading further.

[roywiggins]

Not only does it scream LLM output, I happen to find it almost always grating. It's fine enough when something is labeled as AI output, but when it's nominally a human-authored document it's maddening.

Claude tics appear to include the following:

- It's not just X, it's Y

- *The problem* / *The Solution*

- Think of it as a Z that Ws.

- Not X, not Y. Just Z.

- Bold the first sentence of each element of a list. If it's writing markdown, it does this constantly

- Unicode arrows → Claude

- Every subsection has a summary. Every document also has a summary. It's "what I'm going to tell you; What I'm telling you; What I just told you", in fractal form, adhered to very rigidly. Maybe it overindexed on Five Paragraph Essays

One way I'd describe it is LLMs say lots of things that technically make sense but aren't quite like anyone would normally say it.

And secondly they like to use more nouns for things, in my experience.

Of course all this is just what I observe currently and could well become different for better and worse in future versions.

[kikkupico]

I misjudged the amount of dislike HN users have for AI generated writing. I have added a "meta" section explaining how the post itself was written by AI, directed by my own taste. Here's the meta - https://www.kikkupico.com/posts/vibe-discovery/#the-meta

To be frank, I don't think AI-generated writing is inherently bad. Since there appears to be a strong bias against it, I will stick to writing blog posts by hand.

[butz]

Let me do a quick "vibe comment" here: Is it really you who built the game, when it actually was built by an algorithm after you nudged it in some direction, you even did not know from the start? Please fix title to "I gave instructions to LLM and it generated code for a game".

[GaryBluto]

The end result is interesting but I'd prefer the blog entry itself to be human-written.

[kikkupico]

Thank you for the honest feedback! I'll stick to writing content by hand for future blog posts.

were approaching peak slop every day

Today on the front page there was an obviously vibe coded python script that pulls OSM data and slaps a colour scheme on it. Of course the data was skewed, because apparently LLMs don't do projections...

I gave up on the first non-ironic 'You are absolutely correct' comment... What is even real...
