A good point has been raised!
Since the recent adjustment to how we handle releases came a bit abruptly, I feel those who have donated to us in the past deserve some recognition. If you have donated before, send an email to me at email@example.com with what email you are registered with on http://flexiblesurvival.com/ and how much you've donated in the past. You will get 1 month of complete preview per $15 you already donated at any point up to April, to a maximum of 12(1 year) added to your account. This also counts as a top level subscription on the multiplayer game, if you play that.
Thanks for supporting Flexible Survival,
