The Visit

The Visit is a platformer in which you play as the hero trying to get to his girlfriend's house. On the way, there are crabs that aren't really enemies, they're just walking along the path, but a single mistake could cost you dearly.
We won't spoil it for you, as finding out what to do is part of the game's thrill. Just know that there are multiple endings to this game, and you can find most of them that involve the crabs and how you treat them.
