Hello people, I am just wondering if I encountered a bug on my first playthrough or if I forgot a special door... You see, in the cutscenes, Kain says that he could try to save Starlyn if has enough time, but I ended up killing the final boss without seeing her... After that, I played the «secret level», which ends up with *guess what* saving Starlyn! But in the final cutscene after the boss in hyperion labs, Kain is about to get in a spaceship? So now i'm really confused... Is Starlyn on the spaceship, or is the level supposed to be played before hyperion labs, or is Kain confused himself and went back to save the girl he *cough cough* doesn't love? Also, my first run was on Hardcore and I didn't pay attention to all the secrets. Was I suppose to find the secret level?

TL;DR: Is the secret level supposed to be found before the endgame?
