The whole thing feels like someone took a Daz3D render pack and slapped a barely functional Ren'py wrapper on it. Not that I'm complaining, exactly. You don't come to these games for cutting edge gameplay, you come to watch a blonde with beachball tits slowly lose her moral compass on a tropical island. And Island Sun delivers that specific, greasy satisfaction in spades.
Wendy's husband Henry is basically a cardboard cutout who exists to be ignored. The game knows this. The first time you get the option to let the resort bartender "accidentally" see up her skirt while Henry's grabbing drinks, you realize the whole marriage is just set dressing for corruption. The CGs are that particular brand of 3DCG where everyone looks slightly plastic but the lighting on the sweat and cum is weirdly detailed. There's this one scene with a massage that escalates, and the way her wedding ring catches the light while she's giving a handjob... chef's kiss. Pure trash cinema.
But the choice system is an illusion and we all know it. You click the obviously corrupt option, the meter ticks a little, her internal monologue does some mental gymnastics about how she deserves this vacation, and you get a new scene. Repeat. The writing has this accidental comedy where Wendy will be mid blowjob and thinking about how her husband never appreciated her "free spirit." I wish the milf tag was earned though. She's thirty something but the model looks twenty five with bigger hips, which is a pet peeve. The island setting is just a series of static backgrounds with a slight blue tint filter. No exploration, no real sense of place.
Remember that old Newgrounds game where you'd corrupt a babysitter by clicking increasingly unhinged dialogue options? This is that, but with a resort theme and way more oral sex. The cheating aspect is the whole point, obviously, and it doesn't pretend otherwise. No tedious minigames, just pure, streamlined degeneracy where you steer a supposedly faithful wife into increasingly acrobatic positions with the pool boy. My save file corrupted halfway through the "beach party" route and I genuinely couldn't tell if I missed any content or just got the same scene with a different NPC model swapped in.
