K, so it's been a long time since I last reviewed a game, but...
It's just sudoku, with pictures, and maybe animations. But, well... It's sort of hard to understand what's going on and... I don't really care for sudoku. Me, no brain. Brain off, dick on.
Disclaimer: I did not complete the game, nor even spent 10+ minutes on it. I took a peek, and gave you my first impressions. I took a look at gameplay and the other parts, but to be fair, not particularly an indepth look.
Gameplay, 3/5: Sudoku, but lewd. Lewdoku, as it's called in-game.
So, it's just sudoku. Now, I'm not a big fan of brain teasers in porn games, but for the review, I'll try my best not to take it into account. So, you click on blocks until you get pictures, and like sudoku, each quadrant/area, row, and column must have one of each image.
Beyond that, it's just a... Resource management game? Sort of? You can choose "focus" to get more fans, time, or whatever. You buy some other things which I didn't really look at to be fair.
Like, honestly, the gameplay is fine, for the most part. Now my issue isn't with "sudoku" and it being challenging or blocking the content. It's more-so that it seemingly tries to be an indepth game with resources to make things easier. I personally think it'd be better as to have it be a "level" system, though I guess this approach makes it easier for those who are like me, who'd rather not try to think too much.
TL;DR, it's not bad in terms of gameplay. It's just honestly a little bit... Less. Some puzzle H-Games have more to it, whether it's a sort of visual novel or management game. This is more of a pure puzzle game so if you are only looking for that, so be it. Honestly, I was hoping for a bit more than just sudoku.
Visuals, 2/5: Uncanny, also Poor Quality.
So, the first image I get after completing my first puzzle is a still image; has RuRu masturbating, and some white boxes with black outlines. You know those cheap, low-quality comics you might see online? Yeah, it's one of those type of deals. All it needs is... More work. I think the best approach would be to separate the image and text, or add some sort of text boxes or something. It just feels "fishy" to have it right on the front.
Now, I don't HATE RuRu's model, it's just... Meh, to me. But the overall quality of the menus, the picture, etc. Is bad.
HOWEVER, the main menu's design is reminiscent of a social meed app. So, that's the only really good part, I guess. Everything else is 1/5 in the visual department. RuRu herself is like, 2/5, maybe. "App" design is 4/5.
Audio, 3/5: Will be Annoying After a While.
So, overall the music isn't BAD, just stock music... The sound quality is good, moans are sensual but... Every time you click to cycle through an image (mind you I played a 4x4 first to get to know the game) it plays a moan. Do anything larger... And if you're not too good so you cycle through more. Overall, if it's short and you can quickly solve puzzles, it might not be so bad. But if you have to cycle a lot, it might start to drone into your head a bit.
Overall, 2/5: A Lewd Sudoku Game. Probably the OnlyOne. (Get it? Like, OnlyFans, but, it's the only one in existence? Yeah, sorry).
If you want a porn version of sudoku, sure, here you are. It's fine as it is, I guess. But other than that, I don't know. You have to gather resources, to have an easier time to complete the puzzles, or get more reward from puzzles, etc. It's not a particularly deep game. It's very simplistic and that could be good or bad. I might delete my review since it's very unfair for me to just give my "first impression."
Just note that, my main issue with gameplay isn't, "Oh it's locked behind sudoku they too dumb." Yes, I'm dumb. But I'm also stubborn so I'd be willing to keep trying till I clear it. What my main issue is that it's too plain. I feel like if I wanted to play sudoku, I'd rather play actual sudoku, with a 9x9 grid and numbers; to me I think numbers are easier to count and move through rather than cycling through images.
I'd honestly give it more of a 5/10, but I can't.
