From the forums it would seem that gog doesn't have the 1.4. version yet? How comes? It's been out for over two months now, isn't it?

Four months now since 1.4 is out on Steam and we're still stuck with version 1.3.1 ... and no word from the devs or GOG here. I also tried to contact the developers, but they don't seem to bother answering mails either...

Well, we shall see. They don't seem to be very active in their own forums either, at least not in the Reus forums. Thanks for posting there anyway :)

On Steam there is conversation where someone asked when Gog will see update. The developer of game mention that update on Gog nad Humble is managed by some idiot member of Abbey Games which was asked numerous times to get them uploaded (this is just plain stupid) but still not done that. They wrote they hope to get it done once he return from vacation.
personally i think its called "faceplam" when games get abandoned not due lack of resources or intentionally but due some idiocy going on.
I hope they kick some ass and get build updated.

Looks like they kicked some ass and finally got the build updated :) Version 2.0.4.18 has arrived on GOG.
