I am using the Arduino IDE to program the attiny85. I want to take an incoming analog reading, then based on that reading, output a specific PWM value. Here's my circuit:

and here's my code:

// to run on attiny85

const byte pwmPin = 0;
const byte analogInPin = A2;

void setup() {
  pinMode(pwmPin, OUTPUT);
}

void loop() {
  int analogIn = analogRead(analogInPin);
  analogWrite(pwmPin, analogIn);
}

should be very simple- I have no problems uploading code to the attiny85, and no problems with simple tests like outputting a specific PWM value (not based on the analog read). but when I try to combine the two- read, then write that value, I can't seem to get things to work. In this circuit for example- I get a reading of 1023 (5v) on the arduino micro- instead of a reading of ~ 790 (3.85v) which is what I should expect. I've used a multimeter to verify the voltages in this circuit- so I think I must either be doing something wrong with my expectations of how to wire up or program the attiny85.
