Welcome, player
Long ago at Fazenda da Toca, the capybaras lived peacefully by the lake — until a nuclear plant
poisoned the water, a radioactive spider bit one of them, and she became Zumbara, the dreaded zombie capybara.
At dusk, if you whisper her name, she stirs.
You start with 60 seconds. Each math statement is either
TRUE or
FALSE.
Every correct answer holds her back (+1 s).
Every wrong answer feeds her (‚àí1 s).
Your run ends when the clock hits zero.
Survivors are ranked by who lasted the longest.
