Playing this game is like having Tom Sawyer as your friend.

He's powerwashing a dirty fence. Smiling. Looks like he's having a great time. And the fresh colors look so pretty against the old muck! He makes sure you know just how fun it is to powerwash.

"I want to try that!" you say.

"Ain't no chance of that! I'm having too much fun."

But you *really* want to wash that fence. You offer to pay him $10 for the privilege. He hems and haws. But you need this.
"I'll give you $25!"

"Deal."

Your excitement turns to rapture as you start to clean. You tell passersby about how amazing it is, and they pay Tom $25 to join in the fun, too. You all clean the entire fence. Then you clean Aunt Polly's whole house.

Everyone is obsessed. More and more people clean more and more things. You clean Tom and Huck's hideouts. You clean the vintage Ferrari that Tom bought from all the money you gave him.

You clean and clean and clean. You haven't seen your family in days. You forgot your anniversary date with the love interest you'd have if you didn't waste all your time playing video games. You're fired from your actual job as a doctor for going AWOL to wash things. Your patients die.

Your life falls apart. You keep cleaning. But you will never wash away your sins.

So that's basically PowerWash Simulator, except add aliens. Good game.
