Sync it with GoG for a free DRM, don't see the issue. Not to mention you already have it here without any DRM. To make it even sweeter, Humble Store might happen, with more DRM-free solutions
Oh yes...you are on GOG...I'll buy the game again here then...no GOG connect for now.
But...You'll never update the itch.io build after full release?
Correct. GoG and Steam will be identical copies, so you choose.
Also working on GoG Connect, if that helps :)
