While I bought this game for $9 (and no regrets, thank you), Sleep is Death is worth at least $15. There is a special level of pixelated charm that this storytelling device (as it does not entirely fit into the common definition of video gamein my opinion), and from all accounts this game is awesome. The games stories I played/made on this platform had a whole new level of new-ness attached to them.
So when Jason Rohrer, the creator of this game, tells you that you can buy this game for as much as you are willing to pay for it, you know it’ll make your day. Yes! Though you have to pay the minimum price ($1.75) that covers the cost of the bandwidth for download and payment processing, you get two copies of the game (since this game is two-player only). So, if you will take our advice, GO BUY IT!
