Thanks for your feedback!
We decided to implement choices in Mei's storyline only after she played the game as a way to symbolize how it was affecting her mind, same as the glitches that appear later on.
There's choices that do add extra scenes and dialogues so I suggest giving a try on the other ending. But as you said because of the deadline we couldn't expand the game as much as we wanted to, but we're still happy to hear that you enjoyed the dynamics that were implemented 😁
