Not a big fan of the point and click scavenger hunt. What purpose does it have other than to consume time and annoy the user?
Also this seems to be an ackward plot device to introduce mc to Hana. The family is sitting at a dinner table with food that is rapidly cooling off. However mc has to jump on a subway for at least one stop (train times? every 15-30 mins?) , participate in said scavenger hunt, and then get back. Meanwhile family hasn't moved a muscle for what realistically would have been 30 mins to an hour.
