I really liked how you collected items and quests from people and have to figure out which items are needed for which quests. Sometimes I couldn't figure it out though (e.g. the "interesting place" one).
The guy selling tuna popped up a lot, as did the guy telling me about the "interesting place". Like, dozens of times. I'm assuming that's a result of a low number of interactions having been made in the limited time?
Cool idea, nice execution; some unintuitive things (e.g. trying to understand what to do with the "interesting place"), and some tedium (though that's the life of an NPC, I guess).
