Susi

Susi is a sci-fi story, set in the 22nd century, where we follow the eponymous character, a half-wolf half-humanoid AI, after feeling a bloody conflict against salamanders (also half-AI) that ravaged everything. Seemingly the last of its kind, Susi get to choose the path forward, whether it is destructive for themselves or the salamander, or more (re)constructive. 5 different endings can be found, I managed 4.

Through the POV of Susi, the story explores crudely different human traits (vengeance, avarice, goodness, etc...), showing that even with the disappearance of the human race, and the evolution of the AI in such a way they've left machines behind, the humanoid beings would continue to behave exactly like humans, with their vices and virtues, rather than the animalkind they embody (or a completely different path). Like ghosts, humans still stay, one way or another, influencing those left behind.

Similarly to the bad paths, who often rambled on and repeated itself, the good ending wasn't much satisfying either, having a bit more of an open end to the story, somewhat giving the feeling that the story only actually started at that point, with the passages preceding the final screen upping up the intrigue.

The author also warns on the game page that some passages could be difficult to read, as it alludes to sensitive subject, but the allusions is actually explicit (stated or depicted) and the execution felt more "edgy for the sake of being edgy" rather than making it central to the plot or having commentary on it: (Spoiler - click to show)suicidal thoughts can be willed away or push Susi into destructive suicide, sexual slavery is mentioned in passing once and almost forgotten, living under a dictatorship is played as a twist so to try to force you to take the "high-road" and forgive the oppressor
