Really interesting concept. I love being a P.I. I wanted to accuse everyone and everything! The roomba did it! Confess, you robotic bastard!
I think the feedback I would like to offer is some of the fantasy here feels maybe a little bit incomplete. Like, I'm a brilliant detective, but am I... blind? If I'm blind, how can I read all these notes? If I'm not blind, why do I have to follow a noisy and suspicious roomba around to see anything? Can I not click my tongue or something for some echolocation? Am I a mute too? Am I writing the questions I ask the suspects on a notepad or something?
Now that I write this out, I guess this sounds pretty nitpicky or absurd. But it was really what I was thinking about most of the time here. I guess that's because the experience is rather novel, and I was trying to justify why I was stumbling around in black rooms looking for a clue that implicated that evil cleaning robot.
