I've added achievements and completed the last tasks required for a Steam release, so I hope that there will be no obstacles. Steam's changing policies required me to rework some things, but the plan right now is to not require any patch to play the full game.
If you are interested in Lizzie and John, please check it out when it releases! I tried to show some glimpses of their future while still giving the two of them a satisfying conclusion. If you'd like to see more, please cross your fingers along with me for the launch!
