The Humble Voxatron Debut deal has expanded again. There's four days to go until time runs out, but if you decide to pick up the voxelly indie blaster, you'll now also get a copy of squishy platformer, Gish.

It's worth remembering that if you pay more than the average donation, which currently sits at $5.18, you'll get bonus copies of The Binding of Isaac and robotic puzzle platformer, Blocks that Matter. As with all the Humble Bundle deals, you can pay what you want, and choose how much of your donation goes to the developers, Child's Play and the Electronic Frontier Foundation.

At this moment, The Humble Voxatron Bundle has received $757,593.38 in payments, with 146,195 purchases. It may well clear ONE MILLION DOLLARS before it expires in ... four days, ten hours and 38 minutes (and counting). Head to the Humble Bundle site to get in on the deal.

Your opinion on voxels may or may not be one of unbridled adoration (mine is that "voxel" is really fun to say), but now the Humble Voxatron Debut's venturing outside its voxel-centric comfort zone. Voxely.

First up, there's recent indie dungeon-crawling darling The Binding of Isaac, which combines steep difficulty with imagery that will leave your brain crying in the fetal position in the darkest corner of your face. Then there's Blocks That Matter, a puzzler with a Minecraft-inspired twist. Simply beat the average price (currently $4.73) and all three games are yours. Or, you know, wait until a better deal comes along. Which will be never.

The Binding of Isaac was already quite evil. You play as a naked child fleeing for his life through a monster-infested basement to escape his mother, who has been commanded by god to slay Isaac as proof of her faith. Indiegames note that after the free Halloween update, you will be able to fight three new bosses, four new enemies and collect more than 20 new items if you successfully slay your mother ten times. The update also adds a new playable character, another ending, more achievements, more music, tarot cards and MORE EVIL. The Binding of Isaac comes from one half of Team Meat, Edmund McMillen, and is available now on Steam for £3.99 / $4.99.
