But wait, you don't need Steam in order to buy! In an awesome move (that frankly should happen every time an indie game comes out), the developers are selling it on their website, which not only nets you a DRM-FREE download, but a Steam code as well. It's also 10% off on launch week!
I'm sorry if this post is a little PSA-ish, but I am just very impressed with the game itself and I really support the business model.
Website - With ability to purchase (a DRM-free download AND Steam code) and a gameplay video (sponsored by the Humble Bundle)
Steam Page - With ability to purchase (Steam only) and a demo
