Customer Reviews

A big-breasted Labian girl struggles in solitude, but she is made to “suffer” in a gruesome, merciless, sensual, and grotesque way.
The terror of being beyond redemption and the despair of inescapable death are meticulously portrayed through Seno’s acting and intricate dot graphics.
Overall, the atmosphere resembles a game where you hunt certain beasts and higher-ups, as there are many enemies that seem like they might enlighten you when defeated. If you like that kind of atmosphere, you should buy it!
The Labian girl in the pixel art is incredibly cute and pitiable, but the backgrounds – with their depiction of houses, trees, rusty iron fences, gloomy shadows, and sense of decay – are also really well done… (Confession)
I recommend downloading the trial version if you’re curious about this aspect since I feel my vocabulary isn’t up to conveying it properly. And immerse yourself fully in the worldview…
As for the story, there are no text-based explanations, but this actually sparks imagination and allows me to ponder and analyze various things on my own, which is fun!
Regarding gameplay, it’s about finding strategies while dying, without being sent back to the start of the map when you die. I think even those who don’t play action games much can get into it easily.
Finally, thank you to everyone who has read my review up to this point. I’m happy if I’ve managed to convey at least some of what makes this work great.

First of all, congratulations on the release!
I’ve forgotten when I first learned about this work, but it was well worth the wait. It was really good.

There are quite a few Ryona elements like beheadings, so I think it’s a selective title, but if you like such things and love dots, you should buy it!
Ryona! Erotic! Dots! Sister! Huge breasts! It’s the best! Right now, it’s 20% off, so buy it quickly.

Although I cleared it all the way through, at the time of release, there doesn’t seem to be a gallery-like thing just for viewing Ryona and erotic scenes? It seems. When you clear it, you can equip infinite arrows, so I don’t think it’s that hard to get to where you want to see the scene. In cleared stages, you can also jump straight to boss battles with area select. (But I want a gallery… I wonder if it will be added in the future?)

In combat, the timing between you and the enemy becomes important.
When attacking an enemy that doesn’t flinch from your attacks, it’s best to hit and run without being greedy. It’s more fun to pour all your arrows into them!
There are no recovery items along the way, so the only way to recover lost HP is to restart from game over. (There are also situations where you don’t game over but rather continue… situations.) When restarting, not only HP but also the number of arrows you carry is full. So go ahead and use plenty of arrows on enemies with lots of health who don’t flinch. You don’t need to save arrows at all~!

Now for the main Ryona and erotic scenes, as I wrote earlier, they were very good. First of all, the main character Rabian-chan is very erotic and cute. Also her breasts are huge. The voice by Amami Haruka also enhances its goodness.
And there are various situations such as beheading, petrification, plantization, seedbeds, tentacles, rape, and interspecies sex.
In other words

— シスターはいいぞ (5.0/5)

Just cleared this gamepad-controlled game in under 2 hours while watching the game over screens. The volume is a bit lacking… but when you consider the mesmerizing quality of the pixel art and the wide variety of game over scenarios, I guess it can’t be helped.

However, I want to see even more erotic Reyna and Labian scenes, so I’ll keep playing this multiple times while looking forward to future updates adding more content!
(Personally, I found the game over scene where Labian/Ann is suspended and violated to be brutally erotic and wonderfully sensual!)

— みるくキラー (5.0/5)

I bought it on impulse and cleared it in no time. It’s an irresistible, immersive appeal for horror action fans.
The difficulty isn’t hard, and I felt it was a game meant to fully enjoy the atmosphere.

The judgment is generous, and the range of enemy attacks and their preparatory movements are very easy to understand. However, for those who haven’t touched action games before, I feel like they might need a bit of getting used to as a game.
The dots are extremely polite, and while simple, they are meticulously crafted in terms of action, which personally feels good.
I could feel the creator’s passion and affection for their work. The sluggishness in operation doesn’t bother me.

There are homages to various works, and I was excited as I progressed through the stages. I recommend actually purchasing, playing, and checking for yourself which works are being homaged.

Thank you very much to the creator for this wonderful work.

Ero-cute sister, dot art, Ryona. If you get excited about these three things, then you absolutely must buy this. The price? Super cheap.

・Description of the erotic parts

A dignified yet adorable sister being violated by filthy humanoid creatures and insects in a dirty place. The erotic and brutal depictions are carefully crafted for each enemy, and some enemies even cruelly torment her after defeat. The game lets you simultaneously savor this shamelessness through both dot art and standing illustrations, which is truly exhilarating.

I want buyers to check the details carefully with their own eyes, so I’ll avoid explicit descriptions. Personally, my favorite part was a defeat scene that repeats in the stage before the final one. It’s something that would be really exciting for a sister-themed game, so I highly recommend checking it out.

No, the gimmick of the final stage and how the defeat performance progresses are extremely well-crafted and exhilarating to the max. So I also recommend that part.

The protagonist Raviyan is so captivating in both dot art and standing illustrations that you won’t get tired of just looking at her. The quality is reassuring even for those who are only attracted to the art style. There are no clear lines of dialogue, but her “Haa!” and moans when she moves are sufficiently erotic enough.


Note that the brutal depictions are really gruesome. If you’re someone who gets outraged at seeing a sister being killed in such a way, it’s probably better to avoid this game.
But since anyone reading this review is likely already interested in Ryona, there’s probably no need to worry.

・System description

The combat consists of just three actions: swinging your sword, shooting arrows, and jumping. This makes it very simple and easy to control. Even if you die, you can retry as many times as you want at each stage interval without stress. The boss difficulty is also quite forgiving.

The arrows arc slightly before hitting their target which may be confusing at first, but they become familiar after a few shots. There are limits on arrows but they are fully refilled when retrying as mentioned earlier.

That’s all! Please use this as a reference for your purchase!
