Discovered this just now, a bit late I guess.
I like the play, it makes you feel sad and lonely, exactly as it should, so good point for that.
The only negative thing I can say is that it doesn't evolve at a certain point. What I mean is that this play tells a story, and it's missing the end. You have the desperate walking in the desert, but you have no evolution/changing in the play expressing the hope of surviving (maybe something going higher, faster and feeling happier) or the failure and death with something threatening, big, saying "the hunter gets close and so does death". To sum up, I like it, but I feel something is missing at the end.
