How can we help?

On your own device: your phone or tablet on Android, your computer on PC. Nothing is stored online, so there's no account to sign in to. On Android, your saves are removed if you uninstall the game or clear its storage.

If Android's backup is on for your phone, it can carry the game's data to a new phone when you set it up. There's no other way to transfer it, since we don't store saves on our side.

Choose New Game on the title screen. It clears your progress and starts the story from the first level, so only do it if you really want a fresh start.

Try Easy: every level can be finished on it. It also helps to bring the newest tower you've unlocked, since each land's creatures are weak to different towers. Check the Field Guide to see what beats what.

Keep an eye on the scenery: frogs, glowing crystals, a grazing goat and more appear during battles, and tapping (or clicking) them earns gold. Calling the next wave early earns bonus gold too.

Ads need an internet connection, and sometimes none is available for a moment. Try again a little later. The game works fine without ads, and nothing is lost.

The bonus is only given if the ad plays to the end. If you closed it early, or it stopped because of a connection problem, try again. If it keeps happening, email us with your phone model.

No. The Steam version has no ads and no in-game purchases.

Win the game by beating level 21, The Mosscrown, and a new stop opens on the world map past it: The Heart, marked ∞. There the waves never stop and keep getting harder, with an echo of a beaten boss every tenth wave. Your best on each difficulty is kept. You can leave a run and pick it up later from the same stop. It's on both Android and PC.
