About Broadside
A turn-based naval roguelite on a hex sea. You command one ship and each turn pick a heading on the helm and a firing angle. The wind decides how far you go: with the wind behind you or on your quarter you cover two hexes, close to the wind one, and straight into it you do not move unless an upgrade teaches your crew to beat upwind. Enemy firing lanes are marked on the water before they shoot, so the question is where to be when the guns go off and how to answer while they reload. After each win you choose one of three cards for your guns, sails or seamanship, and the hull changes to match: a sloop can grow into a brig, a frigate or a bomb ketch firing mortars over islands. Islands block shots, and reefs, powder casks, fire ships and whirlpools shape each battle. The free browser demo contains Act I, The Blockade: six encounters ending against the flagship at the Anchorage. The developer, JH-BK, says the game was built in about two weeks with Claude Code and Codex: “I didn't write the code; I handled the design and QA” while both agents worked in separate git worktrees. Made with Godot; mouse or touch, saves in the browser, in English and Korean.
How it was built
Partially verifiedIn a post on r/aigamedev (1 Oct 2026, UTC) titled “Made a naval roguelike in about two weeks without writing any code”, the developer writes that Broadside was built “in about two weeks with Claude Code and Codex. I didn't write the code; I handled the design and QA while both agents worked in separate git worktrees.” The developer plays each build on a phone, uses bot voyages to investigate difficulty and turns bugs into regression tests, and says playing still catches what tests miss, such as a ram connecting before the ships touch. The post does not say which agent wrote which parts.
Named alongside Claude Code in the same post: both agents worked in separate git worktrees while the developer handled design and QA. The split of work between the two is not stated.
Made with Godot and exported for the web (the demo plays in the itch.io page). Claude Code and Codex worked in separate git worktrees and wrote the code, while the developer did the design and QA: playing each build on a phone, running bot voyages to check difficulty and turning bugs into regression tests.

Verification notes: AI use from the developer's post by u/Narrow_Tourist_4095 on r/aigamedev (1 Oct 2026, 14:54 UTC), read from the Arctic Shift Reddit archive on 8 Nov 2026 (no replies archived); the post links the itch.io page. Rules, demo content, controls, languages and engine from the itch.io page and its two devlogs (1 Oct 2026, 08:41 UTC, and 16 Oct 2026, 05:24 UTC), re-read on 8 Nov 2026; status In development, HTML5, last updated 16 Oct 2026. The itch.io page's content field says “No generative AI was used”, which disagrees with the post (see conflicts). Two weeks is the developer's figure for the build. No name, team size or location is stated for JH-BK. The full game (Acts II and III, unlocked by one purchase) is on Google Play for Android, which this site does not list; the web version is the Act I demo. The Godot web loader was checked for AI service addresses (none); the game data file was not inspected. The game was not played.
Development history
The free Act I browser demo is published on itch.io, and the developer shares it on r/aigamedev the same day.
The developer announces the full game (three acts) for Android; the browser demo stays on itch.io.

- Use of AI
- The developer's Reddit post says the game was built with Claude Code and Codex and that the developer did not write the code. The itch.io page's content field reads “No generative AI was used”. The itch.io label may refer to art and other content rather than code, but the page does not say so. (Reddit (u/Narrow_Tourist_4095), itch.io)
