Is this your first game? If so, then it's actually not that bad. Though I have to point out some issues. But before that, I'll state out the positives, or at least what I liked about it.
- The mapping is not that bad. Usually mapping is an issue with people but I wasn't daunted by how the map looked at all. Of course, I wouldn't say it's a masterpiece, since I'm not one of those kinds of landscape critics and there isn't much to say at all, but it's pretty above decent.
- I liked how you done the automated battle. I know there's some tutorial on it lying around here somewhere (Or another forum), but it's really nice.
- Coming Soon, Spring 2008. Reminds me of a movie. Heh.
Now I have some issues to nit pick, take them in consideration, and not aggressive killing-ish ways.
- My biggest issue is some areas of the storylines. It's not exactly the best of storylines, especially considering there are some cliches or a similarity of them drawing around (Such as an apocalypse. I can predict this has to be something about saving the world now, and that's a cliche in itself). I can't do any analyzing except that Hidan is a cocky person (He's confident he's the best, and hopefully he can show it) while Zarashi isn't exactly the person who likes the open battle air, or of that sort (Since he shrugged to join that army). Nevertheless.
- Dialect can be a fickle thing, but this part is nothing important. The refraining of commas is kind of strange in it. I'm used to seeing commas where some of the talking is, but when it's gone, it's gone! :O Oh well.
- Lastly, it depends on your outlook of the importance on this one. The hero has parished, huh? Well, according to many sources (Search Engine of truth!), parish is a Church related branch. I'm sure you instead of parished, you mean perished do you? This is the only spelling error I noticed, but that's probably because of a little mistake (Despite this appearing whenever the hero is mentioned).
I never look at demos. This was an exception,
I was bored. So I'll look forward to this, and any future updates.
