this game very unique and make me happy to play it, but i'm don't know how to connect my account because use formatic and i'm use trustwallet. can someone help me ?
Of course you can connect Trustwallet to account.
First you need to export wallet from Fortmatic and import it to Trustwallet
You have to use built in browser and connect through it.
Go to "dApps" tab below and enter footbattle.io from there.
