About 破壳物语
破壳物语 (Eggtopia: Merge & Hatch Pets in the US App Store) is a free drop-and-merge puzzle game for phones. You choose where to drop each egg; eggs of the same stage that collide merge into the next stage, and each run has a target egg to reach. Completing the target earns pet eggs that hatch into companions of different forms, which go into an album with growth stages and rarities, and skills, high scores and a leaderboard round it off; version 1.2.4 (August 2026) added a pet album. The developer, posting on V2EX as oikewll, describes a long-time player with no game-development background who, after about a year with the watermelon-merge game on Switch, wondered about merging eggs and raising the pets that hatch from them. The developer chose Godot after looking into Cocos and Unity, built a playable demo in about a week in mid-May 2026 and spent about a month tuning levels, the economy and details; per the post, Codex with GPT-5.5 wrote the whole game, Gemini built an admin back end with a Hono API, most of the art and sprites were made with gpt-image and the music with Gemini 3.1. It was released free on the App Store on 2 June 2026, sold by Guangzhou Qupu Information Technology Co., Ltd, and an Android test build is on TapTap under 趣谱工作室, with the launch there listed for 19 November 2026.
How it was built
Partially verifiedIn a V2EX post (15 Jun 2026) the developer writes: “用 Gemini 搭了个前端后台(hono 写的接口)，codex gpt-5.5 完成了全部游戏编写。” (I used Gemini to set up an admin front end and back end, with the API written in Hono; Codex with GPT-5.5 wrote the whole game.) When token quota ran short the developer briefly switched to GLM-5.1 for simple tasks, found the results poor and had them rewritten. The developer says some Python background made the GDScript that GPT wrote fairly readable, and calls the result a mess of code (屎山) all the same. Per the post the demo took about a week in mid-May 2026, followed by about a month of detail work; screenshots in the thread are labelled as made by Codex.
- DeveloperThe developer's next V2EX post (16 Jul 2026) introduces a second game made again with Godot and Codex (ChatGPT) “after 破壳物语 went on sale” (上一款破壳物语上架后). — V2EX (oikewll)
Built an admin front end and back end with a Hono API, per the 15 Jun 2026 post; a later supplement says the background music was made with Gemini 3.1.
The developer decided to start after talking the idea through with ChatGPT, per the post. Most of the art and sprites were made with gpt-image and sound effects with GPT; the post does not say through which product.
Made in Godot (GDScript written by Codex with GPT-5.5, per the developer), with an admin back end built by Gemini on a Hono API. Art and sprites mostly from gpt-image, with Lovart for store posters and the logo; a later update reworked 27 pet idle sprite sheets with GPT and Figma (24 to 32 frames) and a numpy script for background removal. Music made with Gemini 3.1. Per the developer, about 10% of the month went on the demo, 60% on tuning parameters and features and 30% on assets and store paperwork.

Verification notes: AI use, tools and timings come from the developer's V2EX post (15 Jun 2026, 12:16 UTC+8) and its supplements (15 Jun, 20 Jun and 16 Jul 2026), re-read on 6 Nov 2026. The first post links no store page; a supplement of 20 Jun 2026 links the TapTap test page directly. The App Store listing is tied to the developer by its seller, Guangzhou Qupu Information Technology Co., Ltd (seller site eggtopia.quputech.com, the same domain that hosts the post's images), by the TapTap page, whose iOS link points to the same App Store id, and by the developer's second post. Apple's lookup data (6 Nov 2026, China and US stores) gives the release on 2 Jun 2026, version 1.2.4 of 25 Aug 2026, price free, iOS 15 or later, 4+ and, at that time, 5 out of 5 from 1 rating (observed; there is no App Store rating metric, so it is not recorded as one); it lists only English (EN) as a language while the China listing is in Chinese, so the in-game languages are not confirmed. TapTap (6 Nov 2026) shows 996 followers, no score yet (6 reviews), a 热度 figure of 1,240 that is not confirmed to be downloads and is not recorded, age 8+, version 1.2.3 of 14 Aug 2026, supplier 广州趣谱信息科技有限公司 and a launch date of 19 Nov 2026. The developer writes on V2EX as a newcomer and loves Pokémon; the store text and images we saw name no Pokémon and show the game's own pets, so no IP notice is recorded. The watermelon-merge game is the developer's inspiration for the merge mechanic. The Godot app was not checked for AI service calls; the sources describe no AI used during play. Google Play and the developer's later games are not part of this record. The game was not played.
