If you are reporting a problem, please tell us your device, your OS version, and which screen you were on. There is no crash reporting in the game, so your description is genuinely all we have to go on.
My progress disappeared
The save lives in local storage on your device and nowhere else — we hold no copy and cannot restore it. It is removed when you clear site data for the game, use a private/incognito window, let the system reclaim storage, or uninstall the app. If any of those happened, the progress is gone and the game will start from a new haven.
I want to start over
Clear site data for the game in your browser or device settings, or uninstall and reinstall the app. Either wipes the single save entry and nothing else.
The mine did not pay me for the time I was away
It pays what your storage could hold. Storage is capped by its own level and by your house level, so a long absence with a small warehouse fills up and the rest is lost. Upgrading Storage in the Room raises both the cap and how many offline hours are counted.
I am out of energy
Energy refills on its own over time, and again at dawn — the bed decides how much dawn gives back. You can also bake bread at the workbench once it is unlocked. There is no way to buy energy, and none is needed: the mine keeps producing regardless.
Auto Mine seems slower than tapping
It is, deliberately. Auto Mine runs one round every five seconds while a round tapped by hand takes a little under three. It is there so the game keeps moving when you put the phone down, not to play better than you do.
Rats and roaches keep taking my materials
They only appear at night, and only for as long as you leave them there — tapping one sends it off. Upgrading the Ward in the Room lowers how often they turn up, and Bug Spray from the workbench keeps them away for the rest of that night.
Is there an ending?
House level 17 is the top. Reaching it takes roughly ten to eleven hours of play. Everything stays playable afterwards; there is simply nothing further to build.
Is there anything to buy?
No. The game has no in-app purchases, no subscription and no payment mechanism at all. Every number in it is produced by playing and cannot be bought or exchanged for anything.
Does it need the internet?
No. The game makes no network requests. It works with the network switched off, and no information about your play leaves your device.
Privacy questions
The full policy is on the Privacy page. In short: we collect nothing, we receive nothing, and the only stored data is the one local save on your device.
