Retro Game Aliens

Before you know it, you find you're wandering in a residential area in the middle of the night again... Insomnia is rough on a middle-aged man like you. But this is the first time you've come across a girl on the street who is concentrating hard on a game she's playing on a handheld console.

"Hey, could you clear this game for me?"

The girl's sudden request throws you for a second, but you can't pass up the chance to have a "reunion" with the retro games you used to play when you were young. So you take the game console...
