There are some things that definitely need trigger warnings, and the warning for this game is self-harm.
(Spoiler - click to show)This game uses bare styling in Twine, but it's text layout, pacing and link structure are very polished. The writing is descriptive, with some profanity appropriate to the situation you're in. I felt strong emotions during this, first feelings that drew me in and helped me identify with the character, and then feelings of horror as I chose the 'bad' choices later involving self-harm. I didn't know it would be that bad, which perhaps is how the protagonist feels.
A powerful game.
