I, like many other people, played the game over again because I wanted to see both endings. In the final cutscene, as he was walking down the stairs gloomily again, I stopped breathing for a moment because I thought I had done something wrong and gotten the sad ending again. But it turns out he became happy when he got the dog!
In the first part, it's fun to make the giant dog chase you through the walls going to the left. The dog travels through the building regardless of the fact that he's too big to fit in it!
In the first part, the funniest thing to do is to wait until a crowd of sailors is attacking you on one side, then attack and watch a mass of horrified sailor's faces as they go flying.
Wow I survived dying out of age with 1 health left, and unfortunately was forever alone when my girlfriend died from the alien invasion.
A hint to heal: fall with your friend.
