The difficulty of the game was just right. The controls are hard to get used to, but they make sense. When you're just beginning, the game smacks you down so fast, you wonder if it's even possible. Then you start getting some mastery, and then you run into level 5, the hulk wave. The chaos just gets more and more intense.
There was some amazing sensory pleasure about that game. It just *felt* good. Oh, it felt so good to catch one of the humans and hear that old glug-glug-glug sound they'd reused from some old pinball game. Ohhhh, I want to play again!
