ahh no worries. ya It is a bit unclear. so the first letter is just where you start from, you dont really need to type any word with it, and it really makes no difference if you do or do not. the thing you have to look out for is when you type a word, the keys used are indicated as "pressed" (just a little darker) and the keys that are pressed which are also next to the current highlighted word are the ones you can move to.
the goal is to make a path to the Q! which is the closest to the escape key. hope that clears things up. I like the game, but it could use a few tweaks to make it more clear and of course some more balancing can be done :)
