Currently there is the ending that I have basically planned out since the beginning.. and the "bad ending." The first ending did go through some pretty big tweaks, to the point that one decision would lead to the "good ending" or the "bad ending". To be honest I like the bad ending more, which isn't really BAD. Like nobody dies.

I can't really share much more than that unless you wanna get into spoiler territory, but there's basically one huge screwup and that rolls the ball to the ending.
