Why is everyone rating it low because they think there are missing clues...everything is there, it's just kind of tough to figure them out...No, you don't know anyone's hobby/food/zodiac from looking at the environment, you figure ALL of that out from the clues. The only zodiac and food you can get by searching is your own zodiac and your own food (because the character will say "hey, that's my sign!" or "That's my favorite food!". With just those two pieces of information and the clues I was able to figure out all foods/zodiacs/hobbies for all people except I could only narrow it down to two possible hobbies for both keigo and catrina...
In other words, don't rate it low if you can't figure out the hints, just try harder, it's possible, honest.
