So if you thought that was already super sweet - believe it or not it just got sweeter. Three more games have been added to the bundle! They are available to you whether you already paid the average price or want to pay the average price now! (Around $8.23 at the time of writing). Now you also get Lone Survivor (which I'm yet to investigate), the brilliantly frustrating and difficult (but awesome) Super Meatboy, and beloved puzzler Braid.
The bundle has raised nearly four million dollars already and there's still five days to go! But I wouldn't wait! Go and do this now!
