A web game that is playable and open to change
A coding agent builds a playable browser-game loop from an input and a win or lose condition. The running game opens through the cloud machine’s public URL. Its code remains available for changes to the rules, with further levels added as tasks after the first loop has been reviewed.

Game loops, inputs and end conditions
A first loop has a beginning, an input and a win or lose condition. The brief also records whether progress needs to survive a later visit. This gives the coding agent a defined build and provides a way to judge the game before levels, sound or a scoring system extend it. The first playable result can be checked against those initial rules.
A kanban card holds the loop, input and end condition. A small card keeps the first result within a scope that can be played and checked in a sitting. A further level or scoring system can become a separate task after that review.
Rules and coding-agent implementation
The task specifies the exact loop, such as a single-player timed clicking game that ends after sixty seconds and shows the score. It also records whether the build needs sound, images or only shapes and text. These details define the implementation and provide rules to check during play.
The codespace runs Linux with a terminal and VS Code in the browser. Claude Code, Codex CLI, opencode, Cursor CLI, Antigravity and Qwen Code work there with supplied sign-ins or API keys. Tooling needed by the game project can be installed on the machine.
Browser play and follow-up changes
Once the agent starts a dev server, the Public site panel can point the codespace’s public URL at its port. The link opens the game in a browser for direct play and comparison with the brief. This is the same running result a visitor can reach through that URL.
The codespace is billed by the hour while it runs. A snapshot supports stopping the machine and returning later; snapshot storage is billed monthly in credits. Review notes from playing the loop can be recorded on the board, keeping subsequent changes connected to the original input, rules and end condition.
Questions about a web game that is playable and open to change
- What should a first version of a web game include?
- One playable loop can provide the first scope: a start state, an input and a win or lose condition. The brief records whether progress needs to be saved between visits.
- How do I play it while it is being built?
- The Public site panel points the codespace’s public URL at the dev server’s port. That link opens the running loop for play in a browser.
- Which coding agents can write the game?
- Claude Code, Codex CLI, opencode, Cursor CLI, Antigravity and Qwen Code are coding-agent options, alongside other installed agents. Agent access requires sign-ins or API keys.
