Below is links to various youtubers who have done Let's Plays of Peekaboo. There's no order to this and if course there are spoilers so don't watch these if you haven't played Peekaboo yourself!
Be aware several of these are either old versions of the game or made during the time when the bug that didn't allow players to beat the game existed. I'll point out such instances, otherwise the Let's Play is of the up to date and (as far as your concerned) bug-free Peekaboo. ;)
If I don't mention otherwise then the Let's Play is of the up to date Peekaboo.

Thanks to everyone who has or will be doing a Let's Play of Peekaboo! I never expected a game I made 5 years ago to be this well received (relatively speaking).
