[18+/VN] Mysterious and interesting short story about a super agent girl Saku. Unveil missions by solving puzzles and intimate her. HQ anime artwork w/animation, protagonist heroin voiced, great price. [18+/VN] スーパーハッカーとなり、秘密工作員の朔ちゃんと事件解決&H。いろいろな種類のPZLミニゲームがあり飽きない作りとなっている。必須ミッションとサブミッションがあり、自由に進行を選択できるのが良い。朔ちゃんをはじめ絵柄は凄く可愛く、かつHな数シーンに関してはアニメーションし、日本語テキストあり、日本語音声も当てられている。価格を考えると十分以上のアリだと感じた。モ無。 [quote][b]Check out our [url=store.steampowered.com/curator/36364102-Horny-Hentai-Festival/]Steam curator[/url] , [url=www.youtube.com/curatorhhf/]YouTube channel[/url] and [url=x.com/hhfcurator]X(Twitter)[/url]![/b][/quote]

This is one of those games where you go into it not expecting much, but the story is surprisingly engaging. You play as this super hacker that can do anything, as you encounter an agent who tasks you to help her on a mission. That part of the game ended surprisingly quickly. The actual meat of the game outside of the "Scenes" comes from the side missions. Which in my opinion, are far more interesting than the main story. A lot of them throw interesting curve balls in how they play out. For example, the first side mission you get seems like a very open and shut case. A group of students took a weird creepy photo and you're tasked to figure out what's actually in the photo. The photo itself isn't interesting, but for some reason, you are unable to contact the group afterwards. Quite a few of these side missions have a bit of a twist, or an interesting premise, which makes them really fun to do. The gameplay is just a bunch of mini games, they're a decent challenge. But I want to mention a fun aspect of the game, which is them asking you to press a bunch of non-repeating keys. Which basically means you slam your keyboard randomly like those hackers you see in movies to start the ha…

Overall I highly recommend this, best to get it on a discount but has a lot on content for the price. Could there be more H content, sure. More animations, also sure. This is still one of the more surprising H games because there is an actual story and is different than the AI slop, NTR, or corruption games. I played the early access version and honestly that is the best version of this game. Was it shorter yes but the story was great didn't have the additional characters and focused on Saku who is the best waifu in this game, The added content starts at mission Reviewing the Incident and while not bad the devs ramp up the puzzle difficultly which also feels jarring. Admittedly the puzzles in the early access version were fairly simple they didn't take away from the story. The harder puzzles just meant having to spend time on those instead of the H scenes.
