In the bad end Dr. Tetra hits you in the head and blames "trying to attack Mary" on you. He gets you fired from your job, and you get dragged out of the building.
This game was honestly so good, it took me three days to finish but it was totally worth it! The twist in the endings was just WOW! A clear 10/10 game!
Great story line and amazing art, the only issue I had with it is that it was extremely glitchy on everything but the cut scenes, but overall great game!
