The bundle is an incredible deal on over 1,500 indie games and creative work, with an even more incredible amount of money raised as a result of the sale - it's now raised over $5 million dollars for the NAACP Legal Defense and Educational Fund and the Community Bail Fund.

Polygon has a post with some of their suggestions of games to play, but just looking at the list I'd recommend trying Overland, Night in the Woods, Celeste, and A Short Hike as starting points.
