"The Humble Daily Bundle: Melee
Fists fly and swords clash! Up close and personal is what this bundle is about. Pay $1 or more for the punchy 2-D fighter Guilty Gear Isuka. Beat the average price to also add on the heroine-loaded Vanguard Princess. If you contribute $10 or more, you will also get the newly released tactical sword fighter Blade Symphony!
Stab at a good deal. If you bought all of these games separately, it'd cost you more than $29, but we're letting you name your price.
Mash buttons on Steam. All of the games in this daily bundle are available on Steam for Windows. Please check out the full system requirements here.
Support charity. You choose where your money goes: between the developers and two vital charities, the American Red Cross and Child's Play. If you like this daily bundle, a tip to Humble Bundle would be greatly appreciated!"

Vanguard princess has been up a heap and doesnt seem amazing for $ (edit - available in indiegala monday bundle for a buck https://www.ozbargain.com.au/node/144893), the 3rd tier bundle seems meh (Blade symphony reviews as a bit incomplete, tho is $15 on steam), but a buck for Guilty Gear Izuka seems great
As I linked in the main Humble Daily Bundle topic, you can get Vanguard Princess as well as many other games for just $1 from Indie Gala. Not trying to ruin your deal but just letting people know it's an alternative.
