Really enjoyed it! Will definitely play again.
I did have two little issues: firstly, I kept getting stuck on the pendulum-esque sections between surveys. I had my settings switched to "forgiving" so the main section never gave me issues, but the pendulum seemed much more strict. Secondly, similar to cobalt1917, I don't know if the staticky noise that started coming in around survey 8 was intended or not - while I eventually tuned it out, I don't feel that it added to my experience, for what it's worth. But if intended, then it's probably a subjective thing?
Guess I'll have to go back through your other games now. :)
