We want the game on as many platforms as possible, especially console and handhelds, but we don't want to bite off more than we can chew and not reach our milestones, so we're sticking to Windows (and now Mac and Linux due to stretch goal fulfillment!) for our minimum goal. If we're lucky enough to need to consider stretch goals, additional platforms are at the top of our list! We chose PS4 as our first stretch goal because that's the best information we had at the time. This does not mean we're not considering other platforms, or that the platform story ends with this Kickstarter.
Any backer who is entitled to a copy of the game will receive it for their platform of choice, based on which platforms are available (at this time, Windows, Mac, and Linux).
