Aveweto: question is do they give you a steam code, gog code or will you be able to dl it from them on april 22nd
amok: The direct from dev pre-order is Humble Widget, so you will get the game DRM free via your Humble library, and most likely a Steam key. There is a possibility that it will give a gOg key also, as the technical background thingies are there, but so far I think only Defenders Quest is the only game that do so.
edit - however, it does not state anywhere that it is DRM free... hmm.. oh well.
If it's coming to GOG, then it's likely that the Devs will offer DRM-free via other sites as well, like Humble. I could be wrong, though.
edit: actually, the game page on the Humble store shows an icon for DRM-free as well.
