Unfortunately development of Sack Assassin’s has come to a pause.
It will continue but not any time within the next few weeks. I have set up a tumblr (IamFN2K.tumblr.com) which I use for real time updates specifically for my contributions to YMB Arcade. For now, the focus has shifted to Hero Protagonist which you can read about on the tumblr on YMB Arcade.
Sorry … J.G
