Deployed the 16 games built with Codex and GameBlocks. A few examples: Most of my time is actually spent shaping the player experience. Many ideas emerge through playing and exploration rather than from the initial design — the loop seems to be build → play → discover → improve. Is it possible to build an agent harness that supports this discovery loop — not just one that optimizes against a predefined spec? Full game list:

Spent 7 months building a FOSS platform for natural-language chess analytics (No LLM) Hey guys, I've released CHONSE2, an open-source game review platform that offers unlimited analysis and move explanations without using hallucination-prone LLMs, running entirely in your browser. chonse2.com But Lichess is free, so why use this? Some have asked. It expands on Lichess's feature set a few different ways: Full analysis (accuracy/elo estimations/eval graphs, etc) requir

A friend taught me a Slovenian card game two days ago. GPT-5.6 Sol helped me turn our argument into an AI opponent. Two days ago, a friend taught me Sedmice, a traditional card game we play in Slovenia. The rules are simple, but we quickly got into an argument about the best moves. Naturally, I decided the reasonable way to settle it was to build an AI opponent. I wrote out the rules, project specification, architecture, and implementation details, then handed the logic to GPT-5.6 Sol. Ab

最近用 Codex 做了一个 3D 骰子! 最近做了一个很小的网页工具:3D 骰子。 做完后有点纠结: 这种小工具到底应该保持极简,还是把常见功能都补上? 抛骰子: https://wheelpage.com/zh/dice-roller/ Dice Roller: https://wheelpage.com/dice-roller/ 现在功能很简单:打开页面,点一下,骰子滚动,然后给出结果。 一开始觉得骰子就是 1 到 6 的随机数,应该很好做。 但做的时候发现,如果只是直接显示数字,又不太像“掷骰子”;做成 3D 动画,又担心有点多余。 现在倾向于先保持简单,打开就能用,不加太多设置。 顺便也做了一个抛硬币页面: https://wheelpage.com/zh/coin-flip/ 它和骰子类似,都是临时做随机决定的小工具。
