Yeahhhh I'm sorry man, this didn't really work for me either. I don't think this was a disaster or anything, but the tone is so uneven and inconsistent that I'm not sure what it wants to be, and I feel like the VN doesn't know what it wants to be either.
I'll explain what I mean once I get to writing, but I'll just go ahead and jump in, so spoilers ahead.
First off, I want to acknowledge that the presentation here is actually pretty good. Yes, you're using stock jam assets and sounds but I think you do so very effectively, and I appreciate the effort in moving them around, even for short effects like moving a sprite up and down to convey laughter. These are minor details, but I think there's so much emphasis on the writing in the comments that the presentation is getting lost along the way, and I really do think you deserve credit for that. Same goes for the mechanics of the writing - no typos or other errors that I can remember, and the attention to detail there is duly noted.
Moving onto the writing itself, your response to my topline comment might be "It's a story about naked bucks, what more do you want?" but I never felt like that was really all there was to it.
Early on, we get double entendres like "Will you be able to handle a huge load on your back?" and metahumor (or at least metahumor-adjacent) lines like "Damn! What is it with all the hot deer I keep running into this week?" that suggest this is supposed to be satirical and silly, but there are also attempts at (apparently; maybe they're supposed to be part of the joke and I'm missing it) serious discussions about nudism and the severe lasting psychological impacts of nudism-fetish-COVID on the protagonist. Ultimately, the jokes never feel consistent enough for it to feel like a comedy and the worldbuilding is so whack that I can't take the serious parts, well, seriously either.
Like, let's touch on worldbuilding for a bit. Purkka already went into this and I don't want to be too redundant, but let's focus on the following line: "It seems like all anyone wants to talk about nowadays is the latest fashion."
This seems like an attempted jab at consumerism, but the commentary feels half-baked because it, and most of the rest of the VN, presumes that modesty is the only reason people wear clothing. Like, if people did readopt clothing that fast, maybe it's not just because they're chasing shallow trends, but rather that they don't want to be freezing or that they want to wear medical PPE or tell who's on which team in a basketball game. There's a bit in the "debate" about clothing as individual expression, but it seems like we're ignoring all the practical uses of clothing.
There's plenty more about the "lore" that doesn't make sense too. Besides just 20 years being way too short for clothing to be a lost concept, like, why are there no roads leading to the former town? How'd they even get all the clothes there without trucks and stuff? Razing the town for the dump makes no sense, and neither does its current physical layout - why would there be a random chimney at person-height but no other rubble or remains besides a concrete foundation? Why put soil over a concrete foundation at all? How on earth is there running water at Devon's house? If Devon never had the disease, why doesn't he have regular blankets? Does anyone have regular blankets? What about sheets and towels? Some of the stuff about the town might be intended to be tongue-in-cheek, but it's not really written in a way that makes that clear and not just an oversight.
Again, you might say that none of this is the point and it's not that deep, but the world is on such shaky ground that it makes the drama hard to buy into. To that end, we really don't get all that much about our leads either. They both like being naked (one out of necessity and severe lingering trauma) and they both like paw play and that's... pretty much it. Like, we're supposed to buy into this happy ending with Cliff going to live with Devon, but I have no idea if they have anything else in common or if they'll even like each other after a couple days. You can only give so many footjobs before you gotta find something else to talk about.
It seems like you had fun making this and I don't want to take that away from you. To be honest, this is one of many times where I wish I could just turn my brain off and not think about the global implications of a setup, but unfortunately this didn't quite land for me.
