As you can see from the current banner/icons I'm using, the game could use some shinier ones. That's a 32x32 icon, a 64x64 icon, and a 250x60 banner. If you'd like to, make them in the same style as the current ones, except... not sucky.
What do you get in return? Your life is spared by the graw kitty, if that's any consolation to you.
Oh, and I'll put you in the credits or something generic like that.
