So, maybe you should add different endings. Here is my suggestion:
-The very bad ending (Getting scratched by the cat)
The game already has multiple endings:
1- He came back (the original - like you mentioned)
2- The broken ankle (jumping off the roof - again, you mentioned)
3- The chinese virus (eating something without washing your hands)
I can also add “The very bad ending” you said. If anyone else has more ideas about the endings, you can add them here.
