About Protect the Heart
Protect the Heart is a small tower defense game that plays in the browser on itch.io. You build outwards from the heart you have to protect, placing turrets and walls next to the heart or next to structures you have already built, and try to survive 20 waves of enemies with four bosses; after each boss you choose an upgrade. The game's code lists turret types such as basic, flame, freeze, sniper, homing and mine. The developer, dogobgyn, made it for the Vibe Summer Game Jam '26, a jam built around Alibaba's Qwen AI, and says the game was “vibe-coded with Qwen 3.8 max web interface” and that the Qwen 3.8 Max web interface “completely created the game”. The page marks it as still in development. Free, with the source code (one HTML file) published on GitHub under the MIT licence.
How it was built
Partially verifiedThe developer names Qwen 3.8 Max, Alibaba's model, used through its web interface; Qwen is not in our tool list, so the tool is recorded as undisclosed here. The itch.io page says the game was “vibe-coded with Qwen 3.8 max web interface”, and the “AI Tools Used” answer on the jam submission reads: “Qwen 3.8 Max web interface completely created the game”. The jam required entrants to use Qwen during development and describe how.
- Developeritch.io page: “Tower defense game vibe-coded with Qwen 3.8 max web interface.” The AI disclosure ticks AI Assisted, Code, Graphics, Sounds and Text. — itch.io
- ObservedThe repository's commit of the title screen (25 Aug 2026) carries the message “Qwen max did a much better job than coder”; there are 21 commits from 23 to 31 Aug 2026, all by dogobgyn. — GitHub (dogobgyn)
A single HTML file of about 160 kB with inline JavaScript, drawing with SVG and making its sound with the Web Audio API, per the repository; the GitHub repository is named QwenGame and is MIT-licensed. Made during the Vibe Summer Game Jam '26 (25–31 Aug 2026), whose rules required all game code to be created in the jam window and Qwen to be used during development; the developer published the page early in case they got busy and kept updating it until 31 Aug. The page and repository contain no AI service addresses, so the game does not call AI during play.

“Qwen 3.8 Max web interface completely created the game”Verification notes: AI use from the itch.io page and the developer's jam submission (“AI Tools Used”), both re-read on 8 Nov 2026; jam dates, rules and prizes from the official jam page (hosted by MCheca and Haaaaaayden; 33 entries; entries 24 Aug, 22:00 to 1 Sep, 21:59 UTC; voting until 9 Sep 2026). The submission was made “2 days, 1 hour before the deadline”, so around 30 Aug 2026; the itch.io page shows no publication date, so no release date is recorded. The jam's rule that entrants use Qwen is not evidence about code by itself; the code claim is the developer's own “completely created the game”. Because Qwen is not in our tool list, the tool is recorded as undisclosed, with the model named in the text. The host's results announcement (12 Sep 2026) names three winners and Protect the Heart is not among them, so no placement is recorded. The repository was cloned on 8 Nov 2026: one index.html, a short README and an MIT licence (2026, dogobgyn); the game file served by itch.io and the repository copy were both searched and contain no network calls or AI service addresses. Turret types are read from the game's code. Developer: the itch.io and GitHub account dogobgyn; no name, team size or location is given. The game was not played.
