What’s the deal with chests

The code that chooses which letter to press is:

this.letter = 65 + random.getRandomIntUpTo(25);

So it could be any letter between a and z -- mash those keys quickly! (This is easier with a chiclet keyboard where you can just brush your hand across them.) Maybe an invincibility potion can buy you some time?
