Funky sequel to a funky idea.
It's nice, but could still use some working.
Personally, I found it frustrating and annoying, largely because I didn't know where I could and couldn't stand. It really was a case of trial and error and it seems to me that there's no real reason to have any 'detection points' as I'll call them outside the shown field of view.
All that does is force players to either be extra-cautious (boring, taking longer in levels than it should do and not an option often), resort to trial and error (never a good thing) or simply get frustrated and give up.
If you think folk shouldn't be allowed within a certain region, then fair enough, but indicate this!
Also, it'd be nice if you maybe gave folk hints when levels were failed. If the tips were useful, it'd encourage a lot more folk to carry on and understand the game better.
Letting folk use the buttons for going past some dialogue and retrying is a nice touch, but as another guy mentioned, being able to use a button for cheating would benefit all those who like to press keys with their right hand.
I actually really liked the graphics. Although simplistic, everything was really clean and it was far more functional than more realistic heads would be. The font chosen was nice too.
The stylised speech forming a large part of the audio seemed funky to me and the music at the end was a nice pick. However, seeing as it's nearly silent for a large part, it may have been nice to offer an option to turn off the remaining sounds, or maybe have some ambient loops playing during the levels (with an on/off switch).
The story was nice (yeah, I cheated through it) and some of the dialogue was pretty witty. It all got pretty sureal through the end, but the writing was certainly good enough to hang the game onto, providing nice little breaks and helping to generate some empathy.
All in all, a nice idea and a good effort, but getting caught whilst outwith the field of view makes for an overly excruciating experience.
