Hey chuckapitic, thanks for playing, and congrats on finding the secret ending!
When I write a game I'm usually focused on ensuring the characters of the game hold true to their motives, desires, beliefs, etc.
I think the message of the game comes from what the player pulls from the characters.
There is no reality, if I'm being true to my vision of what IAC would say or do, in which IAC says 'yes' of its own accord at the end.
Letting you be the one to 'force' it is a fun bonus that sort of drives that home, but to the average player who doesn't find that I at least hope the ending gave them something to consider.
