Its a very basic and straightforward game that is pretty much a grind with no real effort on the player's part other than minmaxing.
You start off with two actions, two plays, 25k gold, and unlimited time. The only things you have to manage are the beach's atmosphere, sexual desire of women and men, and your own sexual skills. Every day you get gold, depending on how deep into the turns you are, that you can spend on various boosting activities. Your action points and play points will also increase with time allowing you to do more in each act respectively.
Your sexual skill only drops if you didn't improve it that turn allowing you to basically chose the free option once every turn for the low and slow method. The beach's atmosphere only drops if the men's libido is too high as they'll start being too aggressive and scaring the women. Men's libido increases as more sexual stuff is accepted and women's desires decreases every turn (men's libido also decreases early game so it's not an issue for you early on). From there it's just spreading influence, increasing desire, managing libido, until you eventually max out all the sex acts and everyone is constantly having sex and you're rewarded with an infinite play option.
Very simple gameplay with good animations. It's something you can fully experience in about 10 minutes or so but might keep on your drive if you're into exhibitionism and the art/animation style.
