Loving support can help make a terrible condition bearable. Spoiler alert: The story involves assisted suicide, so how you feel about that issue will determine whether you see that as a positive message.
Positive Role Models & Representations
Lots of making out, including a drunken hookup in a parked car, but no sexual pressure or nudity, and nothing beyond "first base" (though a bra is seen). No sexual pressure.
Infrequent, but includes "s--t," " "damn," "ass," "hell," and "oh my God" (as an exclamation).
Ease of Play
Teens drink at two parties and try to drink at a third. It's pretty extensive at the main party, with iffy decisions following. After leaving that party, the two main characters jump in a truck and drive around town. No consequences for any of this behavior -- no hangovers, no regrets for unexpected hookups, no accidents.
