Just a heads up - I randomly decided to try this bundle, I don't buy them all as sometimes I just can't be bothered trying games I've never heard of (as I have so many already).
It's worth your pennies I'd say; I was totally hooked on "Escape Goat" last night, and "Noitu Love 2" is insane fun, it's really well built for PC controls are well. Haven't tried the others yet, though I believe PxelJunk Eden is supposed to be good?
Anyway it has my seal of approval. Go forth and support Indie devs! :)
Oh also they've launched a collector section, anything you've bought in the past can now garner rewards. I unlocked super space rubbish, which is a really fun asteroids clone with upgrades and stuff.
