Hey, thanks for playing the game. I really enjoyed the video!
Oh man, you were so close! When you injected the cure, all you had to do was leave the house through the back door and that would have led to one of the endings. This is not your fault tho so the blame is not on you. It’s a bad game design mistake on my part.
Here is a video of a full playthrough of both endings if you’re interested: https://www.youtube.com/watch?v=BxtksFHsK9s&ab_channel=WowPlusWow
