About Remember My Park
A short, free puzzle game for the browser, in Japanese. An amusement park has fallen asleep and its lights have gone out; guided by the park's mascot, a star rabbit (星うさぎ), you pick any of its three rides in any order and solve two puzzles at each: a combination-deduction puzzle at the merry-go-round, a colour-placement deduction puzzle at the Ferris wheel and a track-connecting puzzle at the mini train. When both puzzles of a ride are solved and you return to the park map, its lights gradually come back, and lighting all three leads to the ending. The developer, 春原美桜 (miosuhara), calls the difficulty very easy and says you can retry as often as you like. Progress is saved automatically in the browser. This is a demo: a shortened version of a planned full game, with all six puzzles and the ending; whether a larger full version will be released is undecided. The developer describes themselves as a gamer of more than 40 years who cannot write a line of code, and makes games by talking with ChatGPT, which drafts the plans and specifications, while OpenAI's Codex writes the code from those specifications. Free on GitHub Pages.
How it was built
Partially verifiedIn a note.com post on how the developer makes games with ChatGPT and Codex (27 Oct 2026), the developer describes a “Mio Verse” development team of named AI characters and assigns the implementation to Codex: “Codex律さん” (running GPT6.1sol or Astra, as the developer writes it) writes the actual code from the design specification and does the implementation work on GitHub. The post adds: “私は1行もコードを書けない素人ゲーマーだが、AIのお陰で毎日楽しく喋りながらゲーム開発が出来ている” (I am an amateur gamer who cannot write a single line of code, but thanks to AI I can develop games every day while chatting happily). The post describes the developer's recent games in general and does not name Remember My Park.
- DeveloperGame announcement (23 Oct 2026), titled “AIに可愛いパズルゲームを作ってもらった” (I had AI make me a cute puzzle game): the developer hopes it shows that a complete amateur with no programming knowledge can make a game like this with AI. The post does not name the tool that wrote the code. — note (春原美桜 / miosuhara)
Per the process post, ChatGPT chat threads (GPT6, as the developer writes it) gather the first ideas, work out the plan with the developer and write the design specification for Codex; a separate thread draws the characters and other in-game visuals, and for complex games a “Work” thread on GPT6.1sol checks the specification for consistency. The game announcement says GPT's new “Intelligent UI” feature let the developer try out the puzzles inside the development chat, and that the first screen design the AI proposed was restyled at the developer's request into a brighter, pop look.
- DeveloperGame announcement: the puzzles could be test-played inside the development chat with GPT's “Intelligent UI”, and the AI's first, understated screen design was changed to a pop style on request. — note (春原美桜 / miosuhara)
Chat-driven development with ChatGPT and Codex on a ChatGPT Plus plan, as the developer describes it: ideas are discussed in a ChatGPT “planning storage” thread, a dedicated development-room thread turns them into a design specification, an image thread draws the visuals, and Codex implements the specification and pushes it to GitHub. The demo is a static web page (HTML, CSS and JavaScript) on GitHub Pages that saves progress in the browser.

Verification notes: Game content, difficulty, the demo status and the play link come from the developer's note.com announcement (23 Oct 2026, 21:49 JST), read through note's API on 7 Nov 2026; the linked page loaded and its interface, puzzle titles and save behaviour were checked in its HTML and scripts, which make no network calls and contact no AI services. The tool roles come from the developer's process post (27 Oct 2026, 22:24 JST), which describes how the developer makes games in general without naming this game; the game announcement itself only says it was made with AI and mentions GPT's Intelligent UI. No AI code share is recorded. GPT6, GPT6.1sol and Astra are the model names the developer gives. The developer's name is the display name on the note.com account (miolog0806); no other identity details are given, and whether it is a pen name is not stated. The developer type is recorded as solo because the posts describe one human working with AI characters; no team size is stated. The GitHub repository behind the Pages site was not read (github.com was not reachable from our checker). The game was not played through.
Development history
The developer announces the game on note.com and publishes the free six-puzzle demo on GitHub Pages; a fuller version depends on player response.
