About 閉店後：深夜配達
A free action game for iPhone and Android, played in portrait with one finger. You are Pico, a delivery robot on the night shift in a shop after closing time: drag anywhere to move, dash out of trouble and use a flash to stop threats, while attacks fire automatically at nearby enemies. Each shift you collect parcels and carry them to the till to meet the day's quota before the shift ends; carrying more at once raises the score multiplier, and chaining combos leads to a jackpot payout. Elite packs, unique and mythic monsters with their own abilities, bosses and a daily bounty drop loot with rarities from common to legendary, along with sets, uniques and runes for sockets and runewords, and gear can be upgraded without breaking. Quotas rise shift by shift across 11 shops, cards add weapon combinations each run and new robots unlock as you go. It plays offline with progress saved on the device, has no in-app purchases and shows only optional rewarded ads. It is in Japanese, English and Korean. The developer, a beginner, says they built it by directing AI coding agents, mainly Claude Code and sometimes Codex and Kimi, starting from the source of a game that already existed.
How it was built
Partially verifiedThe developer's Zenn article says the developer, a beginner, made the game by giving instructions to AI coding agents, mainly Claude Code and sometimes Codex and Kimi, and shipped it to four stores. Rules in the repository's AGENTS.md forbid the agents from pressing store submit buttons without human approval or printing secret keys, and require the checks (Biome, tsc and bun test) to pass before each commit. Large rounds started with a read-only review agent, followed by implementation agents split by file area, each in its own git worktree. Test bots played the game dozens of times to measure difficulty. The article was drafted with help from Claude.
Named in the same article as an agent used occasionally (ときどき), alongside Kimi; it does not say what Codex worked on.
A TypeScript, Vite and Canvas 2D game built by directing AI agents over 17 days of git history (24 Sep to 10 Oct 2026, commits on 13 of those days): 528 commits, with src/ growing from 66 TypeScript files and about 13,000 lines to 229 files and about 72,000 lines, about 1,480 automated tests (bun test), 52 Playwright end-to-end test files and 19 QA rounds. The developer stresses that this does not mean the game was made in 17 days: the first commit imported the source of an existing game (290 files, about 34,000 lines), and the article does not say who wrote that code or how. The article lists the bugs that still got through, among them a joystick that froze and sound that went silent after rewarded ads on iOS, and notes that the AI's own QA scores fell with every extra review and that green tests only cover what the AI thought of.

“開発初心者の私は、AIコーディングエージェント（主にClaude Code、ときどきCodexとKimi）に指示して、モバイルゲーム「閉店後：深夜配達（Afterclose: Night Delivery）」を作りました。”Verification notes: AI use, the agent workflow and the git figures come from the developer's Zenn article (published 11 Oct 2026, Japan time), which says its numbers were checked against the git log and test output as of 10 Oct 2026. The game is classed as AI-assisted, not vibe-coded, because the first commit imported an existing game's source (290 files, about 34,000 lines) whose authorship the article does not state; no AI code share is recorded. The article links the Google Play listing and the official site; the official site names portable nutrition (주식회사 포터블뉴트리션), South Korea, as developer, links the App Store listing, and gives the Google Play launch as 8 Oct 2026, which is used as the release date. Team size is from the Zenn profile line “혼자 AI로 게임 만드는 개발 초보” (a beginner making games alone with AI); the developer is registered as a company. The article says the game was also released on Apps in Toss (a Korean mini-app platform) and ONE store; those listings were not checked, and Google Play is not a platform we list. On 4 Nov 2026 Google Play showed 10+ downloads and 5.0 stars from 7 reviews, rated 3+, and the Korean App Store showed 5.0 from 3 ratings (observed; not recorded as metrics). The App Store rates the game 9+ for infrequent/mild cartoon or fantasy violence; the official site gives ESRB E, PEGI 3 and Korean GRAC all ages. Store names differ by country: 閉店後：深夜配達｜片手ハクスラ (Japan), Afterclose: Loot Roguelite (US) and 폐점 후: 오프라인 로그라이크 핵앤슬래시 (Korea). The game was not played; it runs offline and no AI runs during play.
