This game features some of the most atrocious grind ever featured in a piece of entertainment. I truly tried to get into it and deal with the dozens of hours required to unlock even the most basic content for each girl, but I just can't justify the time -- and no, this isn't a hidden jewel that rewards you for "paying attention to each girl's schedule" as others have put it, the attention to detail required here is about as enjoyable as filling out your taxes... and about as rewarding as about once a year you may get some payback for all your effort. There is variety here, that's for sure, but the characters are shallow like puddles from the morning dew, the conditions for unlocking content are obscure and arbitrary at best, and the graphics are just a notch above passable.
It's just not worth your time, unless you really, really need to hang around some bimbos with breasts larger than their heads and engage in pointless conversations until one of them decides you wasted enough of your time to deserve to see her with a bit less clothing than before, and maybe hold her hand while you walk on the beach… even though every single one of them went to that island specifically to have sex with you, the only man in town.
