Proteus is a beautiful game by Ed Key with no goals except admiring natural features and exploring a procedurally generated island [some spoilers in videos], modeled loosely after the open land near Key's parents' home in Cumbria. The game also features "reactively mixed" ambient electronic music (think 'chiptune Boards of Canada') composed by David Kanaga, which changes and shifts according to your physical context. Though only in v0.1, it has already won critical accolades, as well as an award for The Most Amazing Indie Game at A MAZE 2012.

TIGsource is a blog about indie video games that also has a very active forum community of both amateur and professional indie game designers/programmers/artists. About two months ago one of the forum members (Daid) whipped up a tool to display the art images of a particular thread so he could find something, and it turns out it's a pretty great thing just to browse for its own sake, which you can do here. Updated once a day and, obviously, image intensive. [previous tigsource mentions]

It's not often that a freeware game can truly be called a masterpiece but Daniel Remar has finally released Iji, an action platformer with touches of RPG, in which you control a female heroine with a whole lot of engineered superhuman abilities. What makes this game so good is the sheer of polish that has been put into the production and the large amount of choices there are to make. You can choose what abilities to level up with, whether or not to bother killing enemies and the path you take through each sprawling area, which can effect the outcome of the unfolding story.
