Good, very good.
A strong entry into the visual novella genre. My main cope with them is that there's usually little interactivity involved, so puzzles help to spice things up somewhat. The four side characters are well written, distinct and, while coming down as a bit cliched (especially looking at that certain spoiled brat), are definitely interesting. Story's good and, while it doesn't make a truckload of sense as of the ninth episode, is fun to follow. I especially love the writing, since it's somewhat clever, with some chuckle-inducing jokes and covering of things that may rise up during the game (like cheating attempts and the like). I do feel that the story could use some more hard hits, and not conflicts that resolve themselves after an episode (like the distrust among the group). Some more advanced development of character's traits during the game, despite them being clearly established, (like Rae's lone wolf attitude, Lisa's distrust or Beth's compassion) would be appreciated even more, but since it's only the ninth episode, the slow pacing isn't the problem.
The puzzles have decent variety, and are not as challenging, but still interesting. The main downside is that you don't even need to solve them, since you can learn the solution from your group almost upright without any consequences and repercussions (though i personally do solve every puzzle without hints). Puzzles range from easy (like the infinity one, or the temperature one) to, pardon the wordplay, puzzling (like #26), and i do feel that there could be less "Negative space" puzzles. Other than that, they fill in nicely. There are choises of course, but, as in every linear novel, there's only an illusion of choice (like "Ink refuses to listen" when you don't choose a green door, not even taking about even less relevant ones). I'd also like to compliment the music: it's very good and not tiresome in the slightest.
I'll defiitely check back in a month or two and finish this up and write another review wrapping up my thoughts about the story and the like. As it stands now, this has very great potential. 5/5, 8/10.
[s]Also, what do standings in the extras do? Hope that'll play a role in the future[/s]
