It's a fun cozy game loop of throwing items into the furnace before the big fish guy eats you! First session, I passed the first level easily, with chairs to spare in the third car. Second session, I fed the furnace faster and the fish caught up to me. Not sure if the monster's speed was random or if train speed was affected by the rate I fed it? Also it was fun feeding people to the furnace (I'm not a psycho).
