No doubt there are many indie games out there that people end up never trying due to cost. Some developers simply don't price games competitively when compared to the rest of the indie market. Other times, they do it well, or even at their own expense. Anodyne is one game that has a developer who just wants to get the game out there.
The game cost from $7-$10 depending on whether you buy it on GamersGate or Desura. However, Analgesic Productions have set up a promotion where you can buy the game directly off their site for as little as a dollar. Of course, there's room to add in more funds if you're feeling charitable. The official soundtrack is also available at any price.
Where things get more interesting is that they have also paired up with The Pirate Bay to offer the game completely free to anyone who chooses that method. This is the second game to get such a promotion, the first being McPixel. It may seem bad business to give away a game for free, but it definitely serves to make more gamers aware of Anodyne.
Anodyne is a retro-styled game similar to The Legend of Zelda. Here's the trailer to see if this is a game you'd like to play:
