Finally, a protagonist that is literally me (derogatory). Whose eyes are those eyes?

Takumi is such a fantastically flawed protagonist!! His flaws are honestly what made him as a character and the story itself so compelling.

I love how his shortcomings aren't shown as positive but are still acknowledged and accepted as a part of him as he reaches the end of his story. He's such a tragic miserable guy! I've never read a story with a MC quite like him before. For all his faults you can really see why he turned out the way he did with his backstory in mind...

BIG SPOILERS ABOUT SAID BACKSTORY AHEAD:
The realization that he is a delusional existence is such a compelling tragic fate for him. He is told he would have the traits of someone else entirely if he was made correctly. That his personality was made wrong. With him already having horrible self-image issues to begin with, he starts to see himself as a genuine monster as he saves the world. On top of it all the girl he became a hero for, the girl who he loves, is willing to kill him for the slight chance it would help the "real" version of himself live a bit longer. HOW CAN YOU STILL HATE HIM KNOWING THAT? ITS SUCH A HEARTRENDING ROMANTICALLY TRAGIC ENDING!
AGHHHH!! TAKUMI IS SO COOL!!

My appreciation for the protagonist aside- The way the story slowly unveils its mysteries had me on the edge of my seat always eager to try and guess the next twist. That combined with the fascinating themes of delusion vs reality and the way they are played with made for a fantastic read. Instant favorite for me!

+++Ayase's route is FANTASTIC 10/10 SHES AWESOME

Chaos;Head might be the worst of the Science Adventure VN's (of which I have played most of), but even then it's still a good time as long as you use the Committee of Zero Patch for better translations and QOL fixes. The story is somewhat interesting and the soundtrack is good, but some of the characters (including the protagonist) really drag it down by being unpleasant at best and annoying/repugnant at worst. Which is the point, I get it, but even so it gets old after a while and Chaos;Child was a lot better in that regard. The poor pacing probably contributes to this issue.

Still, if you see it through, it's a slightly above average VN that slowly opens up and becomes better and more interesting the more you read through it. The delusion mechanic is, just like in Chaos;Child, interesting and leads to some weird, gross or funny extra dialogue or opens up new routes. It's just that this and Chaos;Child too are harder to get into and less rewarding to finish than the Robotic Notes games or the Stein's Gate series in my opinion (which are both excellent), but I would still recommend them just for some of the interesting story beats if you can stomach some annoying characters and slow pacing.
