I think Niggles meant the gog codes here came from "the same bunch" that was generated at the time the groupees keys were generated (assuming they were indeed generated much before the bundle), thus having a similar expiration date.

have to check back but i swear some of the early ones had only a 1 month expiry...

That means that Defender Quest devs probably trying to get rid of soon-will-be-rotten codes.

<span class="bold">The Humble Weekly Bundle: Neko Entertainment</span>

PWYW
Puddle (DRM-Free/Steam/Android, Windows/Mac/Linux)
The Mysterious Cities of Gold (DRM-Free/Steam, Windows)

$1
Crouching Pony Hidden Dragon (Steam, Windows)
GAUGE (Steam, Windows)

$5
Wooden Sen'SeY (DRM-Free/Steam, Windows/Mac/Linux)

Poof (DRM-Free/Steam, Windows, Mac*, Linux*)

Includes soundtracks for Crouching Pony Hidden Dragon, Poof, Puddle and Wooden Sen'SeY.

*Poof's Mac and Linux builds are only available for the Steam version.

I thought Neko Ent. went bankrupt (at least the devs of Puddle), whatever.... Cities Of Gold is good for kids but a bit repetitive (lots of stealth and buttons pushing) and better suited for the 3DS.

Another nice weekly bundle, i just grabbed the $1 tier. :)

At a glance this looks like the weakest weekly bundle in a whilem am I overlooking something?

What kind of sorcery is this?! Two weekly bundles running concurrently? Anyway...

I'll personally bestow the "Troll Of The Year" award on anyone with the balls (and money) to end up in the top contributors list and use the username #gamergate! :D

Can I ask what version you run? I've just bought the humble version and my cube stops moving whenever I bump another creature. I can still mess with the menus and look at a map, but the cube won't respond to the arrow keys anymore. So my first attempt lasted 5 minutes. My second attempt lasted 30 seconds.

I found some similar complaints on Steam.

edit:
And those complaints mention, too, that they've just acquired it from humble.

I'm running the version from IndieGameStand. It doesn't seem to a version number that I have found. It is not an installer version, but a packed ZIP that plays from where you unpack it. It includes both 32-bit and 64-bit versions, plus the "Warped Version" of the game, which I've not tried. So far I've encountered no navigation glitches, either with keyboard or mouse, in this version.

EDIT: Bumping into creatures should trigger some dialogue text and data display above the creature. If this is not happening then possibly the game is hanging up on the display. Once the text display goes away you can move again, so it sounds like it's never getting that far for you.

It's nice to see all DRM-free titles, at least in the first tier. I already have Cube & Star & Proteus, so I bought the bundle for LYNE and A Slow Year. Both games look very simplistic but I hope that as the description of the LYNE says, they are both "deceptively simple. Infinitely complex"!
