Score counter for pinball machine

Does this seem like it will work?

  unsigned long currentDebounceTime = millis();
  if (currentDebounceTime - lastDebounceTime >= interval) {
    lastDebounceTime = currentDebounceTime;  // save the last time you lit an LED

It looks like it will only check the OVER switch every half second. Unless the OVER switch always stays closed for more than half a second you could miss it.

void loop() {
  unsigned long currentTime = millis();

  OVERState = digitalRead(OVERpin);  //check the state of OVERpin

    if (OVERState != lastOVERState && currentTime - lastDebounceTime >= interval) {
      lastDebounceTime = currentTime;  // save the last time you lit an LED
      lastOVERState = OVERState;  // save the current state as the last state for next time through the loop

      // if the state has changed check if OVERpin is HIGH
      if (OVERState == HIGH) {
        // if the current state is HIGH then switch1 went from closed to open, increment the counter
        k++;
      }
    }
  }
}
