Bubble Shooter, Built with Codex and Chat: We Need 12 Testers Before Google Play

Bubble Shooter is our new Android game from MTKits. We built it with Codex and Chat, and we are now in the Google Play closed-testing stage. Find it on Play Store: play.google.com/store/apps/details?id=com.mtkits.bubbleshooter. Publishing a new personal developer account still requires 12 real testers before the app can go live.

The game

Bubble Shooter is a casual match-and-pop game: aim, shoot, and clear clusters of matching bubbles before they fill the screen. It is a lightweight Android app from MTKits, with a simple privacy policy and no account sign-up. Open the listing here: Bubble Shooter on Google Play (com.mtkits.bubbleshooter).

How Codex and Chat created the game

This game was created with Codex and Chat. Instead of writing every screen and store requirement by hand from a blank project, we used Codex as the coding partner and Chat as the planning partner: game loop, Android packaging, privacy page, and the Play Console checklist.

• Chat helped shape the idea, store listing copy, and the steps Google expects before production.
• Codex turned that plan into app code, assets, and the supporting pages on mtkits.com.
• Together they cut the gap between "I want a game" and "here is a testable Android build."

That is the same approach we use on MTKits tools: describe the product clearly, let Codex implement, then verify on a real device. Bubble Shooter is the first MTKits title we are taking through Google Play this way.

Why Google Play needs 12 testers

For personal developer accounts created after 13 November 2023, Google Play does not let you publish straight to production. You must run a closed test first.

The official rule is simple and strict: at least 12 testers must opt in through Play Console and stay opted in continuously for 14 days. Only then can you apply for production access and publish the app on the Play Store.

1. We add testers in Play Console (email list or opt-in link).
2. Each person accepts with a Google account and installs from Play Store.
3. They actually play the game on a real Android device for 14 days.
4. The count must stay at 12 or higher the whole time. If it drops, the 14-day clock can restart.
5. After that window, we apply for production access and wait for Google's review.

That is why we are asking for 12 users — or more real players — to test the initial game. Without those testers, Bubble Shooter cannot be published on the Play Store, no matter how complete the build is.

What we need from testers

If you have an Android phone and a Google account, you can help ship this game:

• Open the game on Play Store: https://play.google.com/store/apps/details?id=com.mtkits.bubbleshooter.
• If Google asks you to join the closed test first, opt in, then install from Play Store — not from a random APK.
• Open and play it during the 14-day window so the test looks like real use.
• Stay opted in. Leaving early can drop us below 12 testers.
• Tell us if aiming, crashes, ads, or difficulty feel wrong.

We are recruiting a few extra people beyond 12, because one dropout can delay publishing. Friends, family, and MTKits readers on real phones are exactly who Google wants in a closed test.

Privacy and contact

Bubble Shooter does not collect personal information in the app itself. Ads partners such as AdMob may collect limited device and advertising identifiers. Read the full policy at mtkits.com/bubbleShooterPrivacy.
