Dot Matrix Containment Support

Email marcos@marcosbarbero.com. It reaches one person, and that person wrote the game.

Before you write, the quick answers

“It says I need an internet connection.” The free version does — that is how the ads that pay for it are delivered. The Premium Unlock removes both the ads and the requirement.

“This level looks impossible.” Every shipped level has a winning line that is replayed and verified before release, so one exists. Walls are permanent and the front never moves diagonally — most levels that feel impossible are a corner that wanted a wall two turns earlier.

“I paid, and it is asking me to pay again.” It should never do that. Open Settings → Remove ads & play offline → Restore purchase while connected. If it still asks, write to me with the store you bought from and the approximate date, and I will look.

“I paid, and it says it cannot reach the store.” That is the expected message when the store cannot be checked — the game keeps working. Reconnect and it resolves itself.

“Can I move my progress to a new phone?” Not yet. Progress is stored on your device. A full device backup and transfer carries it, but there is no live sync between devices at present.

“The game is in the wrong language.” Settings → Language — it lists every language in its own name, and “System” follows the device.

Reporting a bug

Useful to include, if you can:

Refunds

Refunds go through the store, not through me — see Terms of Use. Do tell me what went wrong as well, though; a refund on its own tells me nothing.

Response time

Usually within a couple of days. This is not a company; it is one developer with a day job.
