Short answer: there is no other ending.
And I agree with you about it. What is there now is not what we wanted, and we have a plan to change it.
My point was the theme. I will not spoil it, but since you finished, the note says "Trust, No One", not "Trust No One". And you know who you were talking to on the transmitter.
I asked about your time because it gets written under the mode button on the title screen once you finish a run. It can be done in a few minutes, if you ever fancy another go.
