Edge of the Cliff claims to satirise the "non-interactive movement in IF". I do not know which games that author is thinking of, though one would suppose Photopia to be one of the prime targets. The work Edge of the Cliff overtly mimics is Blue Lacuna, which is very interactive -- except for the way you are shepherded into accepting your destiny in the prologue, and perhaps that is the object of satire here.
Poster gives us a very small scenario which always ends the same way no matter what you do. This is none too subtle, but the fact that you can only reach the ending through actions that would not seem to lead towards it is a deft touch. You cannot actively jump to your death, because that would be too much player agency.
As a member of the class of "I'm making a small point with a small game"-games, Edge of the Cliff gets two stars. (The author might want to fix two bugs I found: during the first two questions, random input does not give the desired answer; and one of the endings does not end the game.)
