Have any other Kickstarter backers received their GoG key for the full game through Fangamer?

EDIT - twitter.com/SwordorWhip recently indicated that they are still working on code delivery for GoG.

No. Not yet.

I would have liked to have got a key at least a few days before release so I could get everything is in order.

Not yet...

If you have not received your codes, be sure to check your Fangamer fulfillment page. My codes were posted there, but I did not receive e-mail notification that they were available.

I've already gotten my codes from the Fangamer fulfillment page that was mentioned. I checked the page this morning, I got a notification that said "You have unredeemed codes" show up around 9 AM EST in my area, and from there I found my digital backer codes for the game and IGA Back Pack DLC (the 2018 beta version codes for Steam and GOG where taken away from my page though; I did not have access to the 2016 version since I backed fairly late into the game's development) while I wait for them to put the game and DLCs together for the physical copy I'm hoping to receive when they get all the free DLCs out.

im one of the first moments physical backer, got an alchemist treasure tier and i am in tears T_T wanted it so bad

My friend got the codes, so I expect to playing soon. :)

the game codes are in fangamer redeem page.

no additional email, just get there guys :)
