Ruby Warrior
Write Ruby that guides a warrior up a tower, floor by floor
Ruby Warrior puts you in charge of a warrior climbing a tower. On each floor you write Ruby code that decides what the warrior does each turn, so it can fight enemies, rescue captives and reach the stairs alive. Your warrior gains new abilities as you climb, and you score points for defeating enemies, rescuing captives and finishing fast.
