Tried reinstalling it from here and from Steam, and it still doesn't work, I guess I'll wait for the next update or the full game, LOL.

I had exactly the same problem as you, and after uninstalling, reinstalling, deleting the save files, and starting a new save, I can now move during that phase.
And just so you know, the game will be free, but there’s a Kickstarter campaign going on if you’d like to support the developers and can afford to.
