Wow! I liked how you transition from one scene to another, seamless. This helps immersion as loading screens are also moments in which we invite the mind to disconnect for a while.
The art is great, you conveyed a lot of meaning with just a few polygons, and they are aesthetically pleasing. Did you use a color palette? Your minimalistic stage play looks very well balanced in terms of color, composition and proportions.
One thing that made me a bit mad was the sinusoid wave/ball phase. It works smoothly once you get the ball to get forwards, but I feel that it is too long, too much time without rewarding the player, so in spite is very good looking, it gets frustrating.
About the text, the cashier telling me to GTFO was a great surprise to stablish the theme. Although I would take care of hoy many dots (.) I used. More than three provoke too much noise. As Bukowski said, when you write is has to read "bang, bang, bang"; do not be afraid of using short, strong sentences that start with no dots and end with a single one ;)
Overall, quite a beautiful piece of art! You should develop it further. As I said, transitions made it really cool!
