Gets too hard, too quick
Sorry man, but this game is one that starts off as a great game, but then develops a serious flaw along the way - random letters. For trained touch typers like myself, this poses a major problem, since we're used to reading words off notes and typing away without a second glance at the keyboard, but when it comes to these random letter sequences in hard mode, it really just stops it from being an enjoyable game.
I think you should consider having other things in there for this game, like a system of increasingly longer cliffs to push the boss off and increasingly more difficult words - ones that aren't spelled phonetically, for example.
The limitation of knocking the boss off three times just went a little far, so perhaps with a progression to harder and harder, with an increasingly enraged boss, you'd have a better mechanism for playing this game.
