About Aero Frog Skybound
A first-person 3D platformer that runs in the browser. You play a frog whose jumps carry it higher with each leap, with a double and a triple jump in mid-air, exploring floating islands in a bright Frutiger Aero style to rescue the tadpoles a UFO has taken, four per level. You can also shoot, buy upgrades and use checkpoints in a tower, and the page says your behaviour across the levels decides your ending without any menu choice. The current demo has a training stage that teaches the jumps, two levels and a reworked boss fight. The developer, André Akira (DevAndreAkira), says the game is inspired by Jumping Flash! 2 (PS1, 1996). The page credits “Code: Claude (Sonnet 4.6) + Claude Code”, with the art made with Gemini and Imagen 3, the music with Suno and the sound effects with ElevenLabs. It was entered in AI Browser Game Jam 2, where it tied for 4th overall of 42 entries and placed 3rd for Fun, and in Gamedev.js Jam 2026. Free in the browser on itch.io with keyboard and mouse, and since an October 2026 update also with touch controls in landscape; itch.io lists it as a prototype.
How it was built
Partially verifiedThe “Made with AI” credits on the itch.io page read “Code: Claude (Sonnet 4.6) + Claude Code”, and the developer's answer to “AI Tools Used” on the AI Browser Game Jam 2 submission page reads “Code: Claude (Sonnet 4.6)”. The other credits are “Art: Gemini + Imagen 3”, “Music: Suno” and “SFX: ElevenLabs”, plus “Intro Video: Pippit” on the jam page. Neither source says how much of the code AI wrote.
- DeveloperAI Browser Game Jam 2 submission, “AI Tools Used”: “Code: Claude (Sonnet 4.6)”, with Gemini + Imagen 3 for art, Suno for music, ElevenLabs for sound effects and Pippit for the intro video. — itch.io (AI Browser Game Jam 2, hosted by Focaccai)
Claude Code is named next to Claude (Sonnet 4.6) in the code credit on the current itch.io page (“Code: Claude (Sonnet 4.6) + Claude Code”); the April 2026 jam answer names only Claude (Sonnet 4.6). The page does not say how the two were split.
Made with Three.js and Phaser, per the itch.io page. The code is credited to Claude (Sonnet 4.6) and Claude Code; the art was made with Gemini and Imagen 3, the soundtrack with Suno, the sound effects with ElevenLabs and the jam intro video with Pippit, all during development. The demo went up on 19 Apr 2026 and was entered in AI Browser Game Jam 2 and Gamedev.js Jam 2026. An update on 31 Oct 2026 added the training stage, working checkpoints in the tower, a reworked boss fight, a 3D main menu and mobile controls; the developer says it was built almost entirely on players' feedback from the jams. No AI runs in the game.

“Code: Claude (Sonnet 4.6) + Claude Code”- AI Browser Game Jam 2 submission (AI Tools Used)
- Demo Update: Training Stage, Fixed Checkpoints, New Menu and Mobile Controls
Verification notes: AI credits, controls, features, engine, status, languages and the AI disclosure (AI Assisted, Code, Graphics, Sounds, Text) from the itch.io page; the jam answer and results from the official AI Browser Game Jam 2 and Gamedev.js Jam 2026 submission and results pages; the release and update from the developer's devlogs (19 Apr 2026, 17:11 UTC and 31 Oct 2026, 14:33 UTC); all re-read on 7 Nov 2026. The code evidence is a credit line (“Code: Claude (Sonnet 4.6) + Claude Code”), not a statement of how much of the code AI wrote, so no share is recorded. Claude is recorded as primary because it is named in both the jam answer and the page; Claude Code appears only on the current page. Developer: the itch.io page links a portfolio site, devandreakira.vercel.app, that names André Akira, a front-end and full-stack developer; no location or team size is given. The comparison with Jumping Flash! 2 is the developer's own and describes the inspiration; no source says the game uses that game's names or assets, so no IP notice is attached. AI Browser Game Jam 2 (hosted by Focaccai; submissions 11–30 Apr 2026, 03:00 UTC; rating until 7 May 2026) required development to be at least 50% AI-generated in any discipline, which is not code-specific; the entry was submitted 9 days and 11 hours before the deadline. Results (6 ratings): 4th overall (4.000), tied with three other entries, of 42; 3rd for Fun, 4th for Audio and AI Usage, 11th for Graphics. Gamedev.js Jam 2026 (hosted by End3r and Enclave Games; 13–26 Apr 2026): submitted 1 day and 4 hours before the deadline; 213th overall of 482 entries (2.835, 17 ratings), 87th for Graphics. itch.io shows no public rating or download count. The web build loads only its own scripts, itch.io's script and Google Tag Manager; no calls to AI services were found. The game was not played.
