[H] Indie bundle keys [W] Something fun to play, other indie games

I'm looking to expand my Steam library.

I have

• Humble Bundle 3 key
• Humble Introversion Bundle key
• Plain Sight key
• Greed Black Border key
• Zombie Shooter key
• Zombie Shooter 2 key
• Hacker Evolution Untold key

and I'm not too picky about games. They just need to be fun and be games I don't have.
