Is there a walkthrough for this game? Somebody made a really enigmatic comment on Steam (I don't have the game in Steam. I bought it here from ichi.io) about having to buy the artbook? I wouldn't mind buying the artbook, except I'm not a big fan of electronic artbooks (I'd rather have them in dead-tree format), but I'd rather have just a walkthru. I do VNs because I want just the story. I don't want to have to spin my wheels trying to figure out what choice does what. I'd rather just sit down and enjoy it.
