The options are listed like this: "Name" {the part in quotes is what you have to type letter-for-letter} (Effect of using the attack/Maa cost) If you reach 0 health or 0 maa, the other player/fox wins. If it starts and looks weird, press the flag again.
This game is based on the trilogy Foxcraft by Inbali Iserles. It's a really cool story centered around foxes and magic, and you should definitely read it. I hope you enjoy playing!
