All the 2 friends? :)
Actually, your friends have to be "fans" of IG already to work...

Well, I tried a few times, no luck. I'll try again later, and if (doubtfully) I succeed, it's yours.

No, you don't get any such options in the Humble Store. It's all predetermined.

I have a lot of the games in this bundle but these versions pretty much all include the DLC I'm missing - hmm....

Hack, Slash, Loot is not very good. When playing it, I could not shake the feeling that the deciding factor was in fact not how well I played, but rather how lucky I was. While all rouge-likes has an element of luck, it did feel much larger in Hack, Slash, Loot.

As for Teleglitch, I've not spent a whole lot of time with it, but it seemed pretty good. It's a real time game (and thus possibly, by definition, not a true roguelike), but it does feel like a game that rewards skill & careful planning. And yes, it is good.

It's a pity that Teleglitch isn't drm-free otherwise I would have paid the BTA (I already own Isaac and The Pit). So I paid less than 1$...

Looks like the snuck that one in. Looks like absolute minimum is now 0.16 upwards in increments of 16. Cant manually enter what u want anymore

Only game which I am missing is Sword of the Stars: The Pit from this bundle. Which would quite lot cheaper to get it from Steam. Well don't have that Early Access game either, but got zero interest in it. Well OK maybe not zero. The game looks fine, just not into playing/buying non-finished games.

Click on the green box with the price and edit. So you can still manually enter what you want.

I see. So does it mean each of these five charities receives 2% out of these 10%?

I found this:
"That 10 percent donation will be divided equally among the American Red Cross, the Electronic Frontier Foundation, World Land Trust, charity:water, and Child’s Play Charity."

So it seems that that's the case.

You can customise the thingy still to your heart's content, and pay as much as you want.

Thanks a lot for going extra mile! +1

Btw, can anyone tell me how Dredmor and Isaac handle their DLCs? If I install them, will I still be able to play the "vanilla" version of these games, e.g. are there any options to disable the DLC content for a playthrough or do they automatically mix the old and new?

Dredmor :
On the steam version (i think its drm free anyway - someone said..havent tried it), you get the option to disable enable the Realms of the Diggle expansion before a new game, but no option the the free expansion.Havent got the other expansion on steam though so cant tell u whether thats optional or not

The drm free version from Humble (complete) works the same way as the steam one. Option to disable enabled Realms of the Diggle expansion, but no option to disable/enable the free expansion or the last expansion.
Btw the drm free version doesnt come with the installer FWIW, its just a zipped file with the files/folders inside. Sheesh

Dunno about Binding of Isaac
