Arrow keys. Blue is BAD. It is Boiling Hot Water, so STAY OUT!!! You are made of ice!! You DO NOT like boiling water!!!
Backstory: You are an ice cube, living happily in the land of Glacierville, when one day, a glacier breaks loose and comes crashing into your village. Nobody gets hurt, but iglagier (igloo glacier) houses are destroyed. Your village is in ruins. Suddenly you find that you are no longer in Glacierville, and that you can find all that you need to survive to get back home... You gather up enough snow and ice to keep you cold in this rocky but warm climate. Now you set off towards home.... P.S. Can you find the secret key? (If you do, don't tell what it is.)
