So the Windows Store really did get the new build onto the store in under 24 hours! The latest build of FFSHD is available (but unlisted) on the Windows Store. You you won't find it by searching the Windows Store but you can get it with this link: https://www.microsoft.com/en-us/store/p ... blggh40f5h
This is pretty much the same build as the current Android beta. Compared to the first Windows beta, fishing is easier (if you leave the difficulty set to "beginner"), and there's a second river available to download as though you were subscribed for one week, and an additional river is available by registering an email address.
This one will run through the 14th. I hope to release an official version by then.
