The pay-what-you-want PC Humble Indie Bundle 4 has been released.

The fourth pack's contents are Jamestown, Bit.Trip Runner, Super Meat Boy, Shank and Night Sky HD.

Customers who purchase the bundle for more than the average price will also receive copies of Cave Story+ and Gratuitous Space Battles.

All Humble Indie bundles let you allocate how much of your money goes to the game developers, to charity (Child's Play and the Red Cross) and to the Humble Indie Bundle group itself.

So far the Humble Indie Bundle 4 has been purchased 179,931 times and made $936.493.17 in revenue. The average purchase amount is currently $5.35.

Are these games any good? "Super Meat Boy taps into the exact kind of things I want from a video game - it's bold, challenging and, above all, rewarding," said in its 9/10 Super Meat Boy review.
