Field notes
The seven stages use distinct settings and activities, from connecting a mechanical bridge by reading angles to making pancakes with rounding and estimation. Players choose among three difficulty levels; the page says higher difficulties unlock additional cards, while repeated copies do not change a card’s abilities. Records stay in the current browser, and the site advises saving a backup before clearing browser data.
