Bellow you can see what my GDD looked like for this project. I tend to create very high detailed documents for games, but when it comes to personal projects I tend to go very free-form open ended, as it allows for free-flowing ideas and subsequent changes. 

To convey the emotional burden that comes with dysphoria, I got inspired by actions I do in everyday life, shaving in this case. As I set out to create a "walking simulator" I devised to convey the frustration and burden that comes with dysphoria I added a shave mechanic to the walking. This mechanic is ever present and if left alone it will stop you from getting more information from the game by covering the screen. To ensure that the player pays deep attention to the shaving I added a "slit" mechanic where if the player yanks the razor about too quickly or carelessly they will create a permanent bleed that will get worse with time. 

For the visual language of the game I chose a blend of low fidelity models and shades to both mask any inconsistencies while making everything more coherent, and to simulate the headspace of talking to someone who doesn't necessarily want to be read but simply has to talk. To do that the dialogue scenes are recreated to look like VLC media subtitles or other ripped subtitles on a computer, with the stark colors being intentionally off putting, I wanted simulate the feeling of placing the player in front of a laptop in pitch dark room.
