There are other endings, just the father route basically finishes the game barely halfway through it. I know I was like "damn this is short" at first.
There are three dad endings with two epilogues for the dad (basic + extended) which are basically.
- Clara / Dad rush ending (dad misses the meeting / basic epilogue)
- Clara / Dad full ending (both Clara & Dad take actions that lead to it, since they both have to 'accept' it) (it opens both extended, and extended + swinging)
- Clara / Dad Christmas gift. Clara refuses to be blackmail by Veronica and grows to a point she understands herself and can make her own decisions, which depends on her keeping / not keeping the photo.
Additionally the Veronica ending has dad parts. But more centered from the perspective of her sadist persona.
