Have you ever wanted a typing game that takes after DDR? That's what Bullet Hills is. It's not that easy, either. I love typing games and typically do pretty well at them, as a fast touch-typist, but throwing in the need to stay in rhythm makes it a different kind of challenge. Most typing games reward typing as fast as possible, but for Bullet Hills you have to curb the impulse to be super fast. It does have difficulty settings though, based on what kinds of letters scroll across the screen from all the letters to just X. Added to that are some sweet tracks and shiny graphics. And at the price of free, you can't really go wrong. You can download it for Windows via Game Jolt.
