I'm eagerly waiting for testing out the game. Even a small preview build works; like HyperlightDrfiter; they released a preview build open for a short time on Steam. Can we expect that anytime soon? I know you are busy, but realistically, how long before we get our IDs with our shiny pixel faces? :D
It could take a little while but yes, expect a preview build.
About the campaign goodies, Kickstarter allow to make a single survey so it could be very chaotic at this moment… we are waiting to send all things after the game release.
