Very interesting art style, the simplicity of it really brings out the tension of the story and gives a grim tone to the environment!
The writing is quite solid, dystopian capitalist settings are at an all time high and I personally love seeing people's takes on it! One suggestion I would make is to start the game with the "Play Game/Don't Play Game" screen, then transition to the intro cutscene and tie it with the story for better flow.
The heartbeat sound effect was a nice touch, some heavier and slower paced music would add a lot to the scenes as well as some other sound effects for when the main character gets knocked unconscious or when one of the participants gets shot.
Gameplay-wise: checkpoints would definitely help with replayability as well as being able to skip scenes you've seen before. I was able to proceed through the text using an Xbox controller, adding the ability to select a choice using the controller would also be a nice feature if you have the time and are able to do it!
