It's straightforward. A conversation between someone and a monster, with the option of playing both perspectives, one after the other. As you play through the content, it seems that more options get unlocked.
There is an undo button, but it's not really needed as the option to return to an earlier point to try another option always appears once you finish a playthrough.
It is a pretty short experience which you can probably finish in a few minutes, even if you're planning to explore every nook and cranny. Still, as far as the jam requirements go, long playtime isn't one of them, so I won't be judging the game based on that. The writing scares you a little, makes you think a little, and provides entertainment for the short time you play. I can grant four stars based on that.
