If you'd like to move your village from itch.io to the website:
1. Here on itch.io, click Export under the Log (on phones it's in the menu). It saves your whole village to a .txt file.
2. Open towerandtrail.com, click Import in the same place, and pick that file.
Your heroes, gear and everything else come with you. On the website you can also sign in with Google to keep your save in the cloud across devices.
