I can describe it, I don't know if it will help you. There are two game modes: story and arcade. In both you find yourself on a tangled map that you must navigate going from one place to another, dodging the police, the yakuza and the cuckolded women while you seek to reach the clients to have quick sex with them, collect the money and move on to the next one customer. The further the game progresses, the more cops and cuckolded women enter the scene, increasing the difficulty.
In story mode there are three arcs, each consisting of three days, and your goal is to accumulate enough money to move on to the next arc before the three days are up. The games have no time limit, so you must resist as long as you can and accumulate as much money as possible.
The arcade mode is a little more difficult than the story mode, but the games last 5 minutes, so your goal is to collect as much money as you can before time runs out.
Then with the money you earn in arcade mode, you can buy skins and gestures to give your character more expressiveness.
