From what i remember, everything was on a black background. You played two bean shaped characters, one male and one female, I remember the female one being pink and the male one being orange. The point of the game was to rescue the little bean people's dad from a suburban house.
From what I remember, you started the game by flying into the window of the house, made to look like a dog opening and closing it's mouth, you then landed on the floor of what i remember being the child's room. You then had to leave the spaceship by the landing strip made to look like a tongue, and had to press the left and right arrow buttons to keep on it.
Finally, I remember the cat being the main antagonist of the game.
Oh, and it was on PC.
