The "endings" so to speak are
the 2 game overs in e7 (Val giving up or failing to defeat the Nightmare)
a gameover in Alex E13 (Having low relationship with him when visiting)
and then the 3 (soon 4 as another will be added in the next update) E14 endings: Kidnapped, Alex saves Val, Liam saved Val. Chandra's is unreachable currently but once her e13 is done and updated into the game you'll be able to get a version with her as well.
