Polish for an indie web game usually runs in parallel passes rather than one final phase: performance and load-time work, cross-browser and mobile-browser testing, save/state handling, and ad or platform integration each need their own testing cycle before you submit to any portal.
At a glance
| Fact | Value | Source |
|---|---|---|
| Core Web Vitals measured at 75th percentile | for pass/fail | web.dev |
| Godot web export porting limitations | check before polish | docs.godotengine.org |
| Web Vitals thresholds updated on a predictable cadence | updated on annual cycle | web.dev |
There is no fixed number of weeks – it depends on scope – but polish for a web game reliably breaks into a few passes you should budget separately rather than treat as one late-stage task: load-time and performance tuning, cross-browser and mobile-browser testing, save/progress handling, and ad or platform integration. Each has its own test cycle, and integration testing in particular tends to take longer than developers expect because every target (browser, portal, ad SDK) can behave slightly differently.
Once the build is stable, uploading via developer.playgama.com gives you test results and feedback within 24 hours.
Where the time actually goes
- Performance: check load time and responsiveness against Core Web Vitals; Google measures these at the 75th percentile of real visits, so a build that feels fine on your machine can still fail for a chunk of users.
- Engine-specific web quirks: Godot’s own docs list known limitations when porting a game to its web export – review these before you assume a desktop build will behave the same in a browser.
- Cross-browser/device pass: test on at least one Chromium browser, Safari, and a mobile browser; canvas and WebGL rendering, audio autoplay rules, and input handling vary.
- Ad and platform integration: if you’re adding ad breaks or a portal SDK, this is its own QA cycle – test on every target platform, not just your own site.
- Submission and review: platforms like Poki, CrazyGames, GameDistribution, and itch.io publish or host web games.
Plan for these passes to overlap with feedback loops, not to run back-to-back – that’s what actually determines your real timeline.

Related questions
Should performance testing happen before or after ad integration?
Before. Fix load time and rendering issues first – ad SDKs add their own overhead, and it’s harder to isolate performance problems once both are combined.
Do all web portals have the same review timeline?
No. Test builds early and expect feedback windows to vary by platform.
