Games Checklist for Vibe Coding

Write a short spec that explains what the player does every 5-15 seconds, what feedback they get, and how progress is measured. AI coding tools produce much better browser game scaffolds when the loop is explicit instead of buried in broad creative instructions.

Limit the first build to one mode, one map or screen, and one win condition so the AI does not generate an overbuilt architecture full of unused systems. This is especially important for non-technical builders who need clean, debuggable output from the start.

Tell the AI whether the game should use HTML5 Canvas, DOM-based interactions, WebGL, or a lightweight framework like Phaser. Leaving this vague often leads to mixed rendering patterns, performance issues, and difficult later refactors.

Document whether the game uses keyboard, mouse, touch, drag, tap, or gamepad-style controls. AI-generated code often assumes desktop keyboard input unless prompted otherwise, which creates usability problems on mobile browsers.

Pick a style such as minimalist neon, pixel art, flat vector, or text-first UI so generated art, sounds, and interface code stay consistent. A clear style direction reduces rework when using image models or placeholder assets in rapid iterations.

Include instructions for pause states, restart behavior, collision edge cases, and what happens if timers hit zero or assets fail to load. This prevents common AI output problems where the game works once but breaks after reset or replay.

Request separate modules for player movement, enemy logic, scoring, UI, and audio rather than a single monolithic file. This makes it easier to debug AI output, swap systems, and keep context windows manageable across conversations.

Ask the AI to explain which file handles state, rendering, input, and utilities before writing code. Browser games built through vibe coding become hard to maintain when all logic is merged into one script with hidden dependencies.

Tell the model to keep game state in a single predictable structure and avoid duplicating values across UI and logic layers. This reduces the classic vibe coding issue where score, lives, or timer values drift out of sync after updates.

Request concise comments for collision handling, procedural generation, animation timing, and state transitions, but not for every simple line. Over-commented AI code becomes noisy, while strategic comments help future debugging and handoff.

Prompt for simple SVGs, color blocks, or generated sprites plus fallback behavior if assets do not load. This keeps development moving while avoiding blank-screen failures caused by missing external files or broken paths.

Instruct the AI to use minimal packages and specify exact versions when a library is needed. Many AI-generated game projects bloat quickly with redundant helpers, which hurts performance and confuses deployment.

Open the build as a new player and check if goals, controls, and feedback are obvious without reading source code or prompt notes. Vibe-coded games often function technically but fail onboarding because the AI focused on mechanics over clarity.

Make sure speed, spawn rates, health, score multipliers, and timers live in a settings object or config file. This allows rapid balancing through prompts or manual edits without risking unrelated logic changes.

Test repeated play sessions to confirm timers, enemies, score, particle effects, and audio do not persist incorrectly. Reset bugs are one of the most common failures in AI-built browser games because event listeners and intervals get duplicated.

Confirm that jumping, collecting, taking damage, winning, and losing all trigger immediate visual or audio responses. AI-generated game logic often works silently, which makes interactive experiences feel broken even when events are firing correctly.

Use a temporary overlay for FPS, player coordinates, collision boxes, active entities, and state flags. This is especially useful for prompt engineers and non-developers who need visible diagnostics instead of stepping through code deeply.

Test latency, accidental double-taps, stuck key states, and gesture conflicts in the browser. Interactive experiences generated by AI often feel acceptable on desktop but awkward on mobile because touch handling was added as an afterthought.

Use Chrome or Edge performance tools to check whether animations, particles, or game loops are causing frame drops or memory leaks. AI-generated code often creates hidden intervals, unnecessary redraws, or uncollected objects that only show up after a few minutes.

Review setInterval, requestAnimationFrame, keyboard listeners, and resize handlers to ensure they are attached once and cleaned up correctly. This is a frequent vibe coding bug when the AI patches features in multiple passes without consolidating lifecycle logic.

Throttle the network and verify loading screens, retries, and fallback rendering paths. Browser games can appear broken on first load if AI-generated code assumes instant asset delivery from local or cached files.

If the game stores high scores, settings, or progress, confirm corruption does not crash startup and that reset paths exist. AI tools often add persistence quickly but skip validation, leading to broken sessions for repeat players.

Test rendering, audio autoplay behavior, font loading, and touch input in multiple browsers before sharing the game. AI-built interactive experiences frequently rely on APIs or CSS behaviors that differ enough to break polish or playability.

When something breaks, document exact steps, expected result, actual result, and relevant console errors before asking the AI for a fix. This produces far better debugging output than vague requests like 'the collision is weird' or 'the game freezes sometimes.'

Include the game title, one-line objective, controls, and a clear play button instead of dropping users directly into action. This improves retention and makes the project look like a product rather than a raw prototype.

Track session starts, first loss, level completion, retry clicks, and average session duration using a lightweight analytics setup. These signals help you decide whether to tune difficulty, add monetization, or reposition the experience as a portfolio piece.

Choose whether the game will be free for lead generation, premium as a finished product, ad-supported, or part of a freelance showcase. The monetization path affects UI decisions such as save systems, content depth, and call-to-action placement.

Document setup steps, dependency versions, asset sources, known limitations, and how to regenerate major systems with AI. This is essential when selling or handing off a vibe-coded browser game because the buyer may inherit mixed AI and manual edits.

Capture the hook, key mechanic, and win or fail moments so the game is easy to market on listings, social posts, or portfolio pages. Browser games sell better when buyers can instantly see responsiveness and visual clarity.

Confirm you have rights to use generated images, sound effects, fonts, and any third-party library licenses included in the build. This matters more than many vibe coders expect once a game moves from experiment to paid product.
