I waited to finish this game to make a review, but wow. What a masterpiece. If you plan on playing this, save yourself and DON'T look at ANY spoilers or ANYTHING about this game. This was the first visual novel I ever played but wow, what a journey. 100% worth getting fully price, 10/10 and I will die on this hill. This is the most unserious serious, perverted, hilarious, twisted, psychotic, tragic and wholesome visual novel you'll ever witness. The twists and turns are amazing. NOTHING is what it seems and EVERYTHING is important and relevant. The creators really focused on making things flow together all while keeping you on the edge of your seat the entire way without making it boring. Let's talk story. As much as I dislike some characters, every characters has their moment and are all important pieces in the story which I love. Everything is intertwined and every character has their development. It handles those changes extremely well and makes them fit perfectly. Visually, the art style is great. I didn't run into any trouble running the game and it ran very smoothly (although capped at 60 fps). Now let's talk game mechanics. This is a visual novel so obviously there's gonna be reading, but the game makes it not boring where even it's a lot of dialogue. There's a lot of freedom with picking your dialogues and it can lead to hilarious exchanges that are 100% worth going through. The somniums are well balanced where it can be trial and error and you may have to restart, but it does a good job to hint you enough that you can figure out everything by yourself without holding your hand the entire time. Extremely well made. You have a lot of freedom during them too which is nice. If you're an achievement hunter, the achievements for this game and the secrets are pretty easy to get and you could just get them all while playing if you take your time. Overall, this game is extremely well made. I cannot recommend it enough. This set the bar VERY high for my first visual novel and I cannot stretch more that this is an amazing game. Not too long and not too short. Expect between 15-25h of gameplay, all worth your buck
Did you play the Zero Escape games? Then you should like this enough, this is by the same dude. There are a lot of dirty jokes and innuendos that might put you off, which, if they do, fair enough, they didn't land with me a lot of the time either. But it's worth looking past it for the story here, it is very good. This game made me go "well ♥♥♥♥♥♥♥♥ wtf" in a good way. Made me tear up a fair bit too, some stuff hit too close to home. It took me a long time to begin figuring out actually what's going on, they did a really good job and it is very satisfying when it all starts coming together. One of the better VNs I've played and I've played a fair bunch of them.
I learned Japanese by going into this game cold, looking up everything everyone said, and then adding each new kanji I saw into Ringotan which tests you on handwriting them from memory. I can now handwrite some 3000 kanji from memory, and comprehend an extremely high amount of Japanese. One of the best series for breaking into native Japanese media as a beginner, because it has voices on almost everything, a log you can replay all voiced lines from at any time, and a decent mix of dialogue and narration. Would I love it in English? Honestly, I don’t know. But as a learning tool, it’s absolutely perfect.
