This is a great lil game! Fun to play, I really like the stylistic visual choice, and the voice reminds me of the "bop it" voice lines and highkey really like that you made a game about disc scratching!
For the first few minutes I was a little confused on how fast or slow I needed to turn, but once I spotted the little hands on the bar on top everything became clearer!
I reckon instructions could be clearer, a little line that explains to look at the top to check the target speed, or a pointer to show the "sell it" when the phone goes off. Not the most complicated concepts, but it would definitely help the player to know what to look for, especially when visually you have a very magazine collage style that pulls the eyes everywhere and nowhere at the same time (unclear visual hierarchy).
I hope more people see your game!
