I think your game feels unique and interesting. You successfully achieved the retro aesthetic and I think your voice acting was a nice addition despite your self-criticism.
However, while the story mode initially seemed to have a decent length, I felt like it was missing some key aspects after the last customer. Although it was good, I believe it could be even better with more interaction and elaborative context.
I was also curious about your plans for the future. If this is your first game, I apologize for being a bit harsh in my review, but I see a lot of potential in you and I wish you all the best in accomplishing your goals.
