A Petal Among Thorns has many things going for it but also several things that, depending on personal taste and preference, may seriously detract from the overall experience.
The game is your typical father / daughter story. You can customize the relationship status before the game starts, but it's blatantly obvious that this was meant to be a father / daughter story, however you can make Petal your roommate or whatever you like.
The daughter has secretly harbored feelings and desires for her father for several years (this is the reason given for why Petal is so forward with her advances towards her father). The father has been absent from his estranged wife and family for a year because he went on a stand-up comedy tour that never really amounted to all that much though.
But the father has returned now and he goes on a weeklong vacation with his daughter Petal to reconnect with her. They have rented a cabin and this is the setting throughout the (short) game.
And of course father and daughter get closer, they tease each other, the teasing results in some awkward puppy roleplay, then things get steamier and the game more or less follows the apparently mandatory progression route for sexual relationships in VNs... the progression and the plot are entirely predictable and it ends exactly how you think it will.
This is mostly a sweet / wholesome romance, but not everything was to my liking. I did not like at all the puppy dog roleplay, I also found it a bit silly that Petal is so self-conscious about her body that she won't undress or reveal her body (she covers all the important bits with her arms and hands when undressed for a very long time) after doing several quite naughty things with her father. And when Petal finally shows her body it's of course your typical 10/10 goddess body that no one would ever feel self-conscious about.
Teasing is often a good thing but I feel the teasing eventually outstays its welcome here or becomes a bit silly and unrealistic.
I am also not a fan of the blindfold Petal wears for various scenes (nothing you can do about it) and I am especially not a fan at all of the unavoidable handcuffs she wears when things reach their culmination towards the end. They do get eventually removed in the final scene, as well as the blindfold, but with this being Petal's very first time it just feels odd and very wrong to include it at all. This ruined the mood for me in the final scene. Make these things optional!!!
And while I know that this is all a fantasy and inherently unrealistic I think it stretched things too far when Petal eventually reveals to her father that she'd love her sister to also get close to him, since two daughters are better than one... right? (her words)
There is also an unskippable scene with the father masturbating to a lewd photo of the other daughter Bliss while Petal encourages him.
I suppose this is meant to set things up for the sequel (which I have not played and probably will not play based on the reviews I have read) but it had no place here.
This should have had a focus on the daughter / father dynamic without hinting at Petal being yet another (bi-curious) sharing fanatic that far too many VNs feature. Completely unneeded in this context and this type of story.
Also, a game that is all about the teasing needs a killer scene at the end. But the scenes at the end were just... very disappointing.
There is no foreplay , no tenderness, not even kissing. Just in and out and bam, that's it. And then the next morning it's the same, in and out on the breakfast table in two positions, but without foreplay, tenderness or anything that would enrich the scene. That felt entirely anticlimactic after all the build-up and made the entire journey to this point less worthwhile for me.
Of course creating animations is very time consuming, but I think a few static renders could have been added to the final act between father and daughter to make it look and feel special.
On a technical level A Petal Among Thorns is one of the better DAZ experiences. While Petal looks stylized (she has anime eyes and generally looks a bit like Alita from the Battle Angel movie) she's cute and pretty. The MC is yet another invisible protagonist who never shows his face. I feel this decision was a major mistake, since it extremely limits camera angles and what kinds of interactions the game can show between the MC and the daughter.
This needed a fully visible MC and generally more interactions between the MC and Petal, but those usually require that the MC is fully visible with his head. Since he's not you won't get several things here that you would otherwise expect. Oral sex is very one sided in this VN, for example, it's only Petal doing things with her father. That was very odd.
All in all A Petal Among Thorns is ok, it's your typical rushed father/daughter fantasy with lots of teasing that uses the typical progression system in these kind of games, which makes everything very predictable. There are foot massages, there is a changing room scene, there is yoga (always yoga...), handjobs, blowjobs, some rubbing, teasing with the tip etc etc and then more of that until at the very end both Petal and the MC are sure they want to do "it".
It's a bit unfortunate that all the teasing never results in a really satisfying ending scene (too short, not elaborate enough) and a game like this with only one or two actual sex scenes needs that, in my opinion.
And again, for a mostly wholesome romance the handcuffs and blindfold both felt wrong, as well as Petal telling her father to also go after the other daughter so they both can pleasure him. I didn't like that at all it felt extremely silly.
A Petal Among Thorns at least looks pretty, Petal is cute and sexy, but for a story focused VN the plot and overall progression through the romance is just paint by numbers. And the lackluster final is just thoroughly disappointing. It would have been better maybe not to have any animations before that and to invest all the resources in one proper and long(er) scene at the end that pulls all the stops instead of being so boring and very short.
Also, don't expect too many meaningful choices, this is a linear story, which is ok, I have no problems with that. But certain (very mild) kinks should still be optional altogether.
I had hoped for more, for a more original romance that doesn't follow the overused progression route, for a daughter that has not been secretly lusting after her father for years and who - even before she ever has sex - encourages her father to go after the other daughter so he can have them both at the same time. That's just plain bizarre.
Petal should have been more innocent for the story to work. And the very mild BDSM felt entirely out of place here. Include it for those who want it, make it avoidable for everyone else. But in my opinion these things were entirely unneeded and wrong to include in the first place. Your mileage may vary of course. But I can't see how BDSM fans will find the extremely mild scenes with Petal even remotely interesting.
