If you’ve never played Bastion or have beaten it so many times that you’ve got it’s music constantly stuck in your head then you might want to check out the early build of Bastion at PAX East. That’s right, the first demo from way back in October 2009 will be available to play at the PAX East show floor. From what you can see of the picture above the main character of Bastion back in the day looked like a knight and the world around him is just a bunch of blocks. This is understandable since this was the very first prototype.
You can find Supergiant and their early build of Bastion behind The Behemoth apparently on the PAX East show floor. If you have not played Bastion yet then you might want to check this early build out and then go and play the actual demo on Steam.
