So, there's a bunch to say about this game. First of all, everybody should play it as it is not praised enough overall, for a VN released a decade ago and being remastered and bundled-in, in more recent years almost nobody has seem to have played it. I certainly haven't, tried it once because it came on a Nintendo DS ROM pack I downloaded off the internet, and didn't really stick with it.

Now, getting to the present; Holy shit. This is certainly one of the best written mystery, thriller-esque closed doors type of scenario I've experienced in a long while. Everything is so damn good, ranging from the escape rooms themselves which set off a good test for your skills on puzzle-solving in general, to the characters having something to attribute in general and being so well written, to the music being pure brain-food puzzle-solving-techno, to the setting being a sci-fi gloomy atmosphere, reminiscent of Children of Men, to the story being one giant mystery with layers and layers to unfold one after another, it even tickles the 4th wall a little bit.

It's just absolutely great. Everybody should play this if they're interested in any sort of "killing game" type of novel, It's safe to say that this one VN is better written than a lot of them.
