Where to write

mounaji.studio@gmail.com. It is the same address listed on the Play store page, and it reaches Mounaji Studio in Córdoba, Argentina.

There is one small studio at the other end, not a support department. We read everything; we will not pretend to a response time we cannot guarantee.

What to include so the first answer is useful

A bug report with these five things can usually be reproduced without a second email — and a bug that cannot be reproduced cannot be fixed:

• Your phone model and its Android version.
• The game version, which is on the Play listing under the install button.
• Which mode you were in: Arcade or Campaign, and roughly which wave or level.
• What you expected to happen and what happened instead.
• A screenshot or a short screen recording, if it is something you can see.

Things you can settle without writing

Progress lost after reinstalling: that is expected. Progress lives on the device and there is no cloud save, which is the other side of never asking you for an account.

Too many ads, or an ad that will not close: note the moment it happened and send it over. We cannot change a specific ad, but we can raise it with the network that served it.

Wanting your data deleted: there is nothing of yours to delete on our side. To break the advertising link, reset or delete the advertising ID in Android Settings → Privacy → Ads.

Reporting something serious

If you find a security problem, write with the subject line starting "SECURITY" and describe what you found without publishing it first. We would rather hear it from you than read it somewhere else.

If an ad shows content that should not be in a game rated Everyone, tell us with the date, the time and a screenshot. That goes straight to the network that served it.
