This is what I picked up from my back-log. While I've never played Vampire Survivors specifically, I have played games with similar gameplay and found them to be fun, which is why I picked this up too. Well, that and based on the previews, the art-style looked nice, so I said: "Why not?"
Sadly, I ended up with mixed feelings about this game. It's a solid VS clone from my messing around with it, but it's not what I'd call a proper hentai game. By that I mean that you could take out all of the adult content completely and it'd still be a solid VS clone. There's also not that much H-content to begin with. There's 5 girls, each with 2 "scenes", for a total of 10 scenes... and you have to play a bit for the second set of scenes since it's locked behind Affection 60 for each girl. It's not particularly hard to get them tbh, but if you don't like this style of gameplay, you likely won't enjoy the reward for it either.
The scenes are... not really scenes tbh. It's just a sex animation with minimal interaction points. That is to say, you can control what bits of clothing are on or off, you can jiggle the girl's breasts, and you can control the speed of the fucking (or of the handjob in the case of the 1st girl's 1st scene). There's some random poor attempts at dirty talk that get repeated, plus a line when MC pumps them full of cum, but that's about it.
You LITERALLY don't lose out on anything if you grab a save with everything unlocked... however, there's so little overall H-content in this game that, unless these girls and art-style REALLY hit some sort of spot for you, I don't recommend picking up the game just for the H. The whole thing is super-vanilla too, so don't expect any kink representation or anything either.
Basically, don't pick this game up for the smut alone, it's not worth it.
Don't pick it up for the story either. There's basically nothing there. The so called war with the aliens isn't elaborated on at all. There's no particular development related to the random battles. There's no real ending. You just have some poorly assembled excuses for MC to fuck a bunch of hot chicks. That's it.
What this means is that you should really only pick up this game if you want a decent VS clone, in space, with some H-stuff attached to it.
Now, I call it a decent VS clone, but how much that is true is one of those "your mileage" will vary. Unlike the original VS or some other clones I've seen of the game, Wings of Seduction has been... simplified, in a number of ways. What I mean by that is that you don't have different characters, you just have the ship. You can select a Main Weapon and an "Annihilator" freely before battle, along with a couple of passives that you can unlock. Weapon growth and upgrades don't really depend on anything. Any valid upgrade path can pop up once a level-up happens, you don't need to meet any pre-requisites or anything. This means that as long as you pick your weapon of choice, there's only RNG getting in the way of getting the weapon path you want.
The only complexity of sorts comes from the Weapon Mods. Weapon Mods are things that are dropped by elite enemies, obtained at lvls 10, 20, 30 etc, or through the use a certain passive. They modify weapons in various ways, varying from affecting a weapon's basic stats, to adding debuffs on-hit, to certain special effects. The combination of specific weapon mods and specific weapon types is pretty high... but there's plenty of dubious mods of dubious utility too. (Eg. The mod that spawns a drone every 24 kills is fun, but it's useless beyond normal difficulty on account of the fact that the damage per attack is equal to the ship's level, and that's just not high enough to make much of a difference.)
There's plenty of things to play around with, but as with other games of this type, the number of combinations that are actually valid at higher difficulties isn't that amazing... though I personally haven't experimented with anything beyond hard. There's not much of a point to it, at least for me. The rewards from hard are high enough to let you unlock everything else easily enough.
Another thing to note is that the game doesn't have "maps" in any real sense of the word. You fly in empty space, with the only other thing out there being the enemies. There's no terrain or anything of that sort, no space debris, no asteroids, nothing. So from that particular point of view, the game has its issues.
WoS adds some variety with its "missions", one for each girl. The missions have different enemies in them, with different focuses, and of course, a different boss. For example, the first girl's mission has special enemies and elites that focus on projectile attacks, and the boss's main attacks are also projectile attacks, aside from this ramming thing it does from time to time. What this means is that on this stage, Light Field with Projectile Erase is really strong. Set it up right and the boss is literally a joke. On the other hand, the second girl's stage focuses on enemies that have "nova" attacks around them with short range. Flying mines, elites that cause explosions around them and a boss with similar tendencies. So on and so forth. It's fun, though it's also worth noting that this stuff doesn't really apply to Endless Mode. In Endless Mode, all sorts of enemies pop up once you activate it. Except for bosses... I think? I didn't mess around much with Endless Mode, so I dunno if bosses show up if you survive long enough or something...
Either way, the game isn't bad per se... but honestly, you run out of things to do pretty quickly. Other VS clones have more creative unlocks for the various things you can unlock. Stuff like beating a certain number of enemy types, surviving a certain amount of time on a specific map etc. WoS doesn't really have that. All of its unlocks either depend on number of missions played, money, or reaching certain stat milestones during a mission and of course finishing said mission. That's it. No "kill x enemies with X weapon using X mod" or anything fun or genuinely challenging.
All in all, if I was willing to bother with the rating system, I'd probably rate this around 3.5 stars? It's not a good H-game. It's only a decent VS clone. It's not super interesting mechanically. It doesn't have much of a story. Which means that it's an ok time waster, but that's all that I can say about it.
