We received a lot of requests for the game to be available on PC. After much deliberation, we have decided to give it a try on Steam for Windows and Mac. But we need your support to get it Greenlit. Please upvote us at http://bit.ly/1fY3VK3.
You get to play Bucky for free if you pledge Entree tier and above. We will send Steamkey/Mobile Code to you straight to his route. You don't have to go through the hidden route to play him (you could if you want to).
Otherwise, when the game is released, you will need to purchase all 5 characters stories (all on the same platform, no mixing allowed) AND go through test and trials before you could play his route. His route is a bonus route which we want to reward everyone who supported us. Just that backers get him easier =D
We will send out a survey form after the campaign is finished. You get to choose between Steamkey (Win/Mac) or Mobile Code (Android/iOS). You cannot get both. If you would like to play on PC and mobile, you have to purchase 2 times.
