beach is a short Twine conversation between two individuals on the beach, which was initiated by one of the two following an incident (implied to be suicide). You are asked to share your feelings, which sends you down towards one of three paths, of diverging length.
Some more uncomfortable to read than others, with your interlocutor trying to make your feel guilty for your past actions, shaming you if you do not feel that, as if you had been the cause (or at least catalyst) for the incident - while, in reality, they admit that no matter what you would have done, it was always going to end up this way. It is pretty manipulative, trying to put you at fault, asking of you to never forget them.
It’s telling that the word sorry is only utter by you, and not them.
