Please, *Please* consider adding just that entire text block on the stats to a "how to play" or "information" tab on the menu. I don't mind struggling with the puzzles (somewhat), but I dislike struggling to understand the base mechanics. Not a lot of players are going to look in here before diving into the game, after all (I certainly didn't).
Until this very second, I had no idea about what dissonance and cohesion did. The time was self-explanatory enough, though I would wish for a "day of the week" somewhere in the UI. If I forget what day it is, the only way I know if I need to go to school is if its the only option in the wardrobe, which isn't great.
Also, to be fair: Kari doesn't tell you to "meet her at the mall at X time," she says she'll "Pick you up after school." I personally took that to mean from my house. Then there was a lot of travelling back and forth and reloading trying to figure out when and where I was supposed to be. I would suggest making her statement more clear and direct; "I'll see you at the mall at dusk," or something to that effect
