How is the play, The Forc’d Marriage, an example of the tragicomedy?

Tragicomedy is a genre that began in Elizabethan and Jacobean drama and was revived during the drama of the Restoration period (post-1660). Tragicomedy mingles comedy and tragedy. The comic action often involves young people in love who are wanting to marry. However, some unforeseen obstacle results in a romantic tangle that seems impossible to unravel, so much so that the plot appears to be leading to tragedy until a reversal of circumstances ensures a comic (i.e. happy) ending. The Forc'd Marriage is a comedy in the sense that a father or other authority figure (in this case Orgulius) obstructs the course of happy love by imposing an unwanted marriage. The play moves toward tragedy when Alcippus strangles Erminia, after which for several scenes the characters believe that Erminia is dead and the audience is unsure about the truth of the matter. The audience also wonders what penalty Alcippus will pay for his crime. The play returns to comedy with the discovery that Erminia is alive, the king's acceptance of Philander's desire to marry her, and the pairing of Alcippus with Galatea.
