Good game, but I've seen better...
You spend most of your time scrolling through messages, especially in the last and first chapters. You're on a wild goose chase for your father, just to tell you about some freaky program, and also going after your Aunt Jessica after she went out looking for him. I thought, "Yeah, this'll be fun, like a cool adventure or something". But, after ten minutes of gameplay, I started to think, "Okay, you need instructions for all these puzzles. She says "Maybe I need to turn the lever" and I say "Well, How do I do that?" And then I bring my DS down to the basement to look up a FAQ. Worse enough, you have to save before the start of Chapter 6, because you can not save after that, so if you pass out from scrolling through all the messages, you can't turn your game off for the next day.
The title says my short version opinion: Good, But I've seen better.
