Modify Arduino code (add piezo buzzer to a working digital hourglass)

Hi, I have a working piece of Arduino code for the Uno / m328p that operates two 8x8 SZ410780N LED matrices through 4 x 595 shift registers (standalone m328p schematic attached) and turns it into a digital hourglass.

The attached source code works great. It uses a pot to adjust the amount of measured time. It also has two tilt sensors to detect position of the hourglass and move the "sand" accordingly. There is a reset button to reset the countdown.

Now, what I need is a piezo buzzer added.

I need it to do the short "tick-tock" sound for each motion of the "sand". And I need it to make an alarm sound for 20 seconds - "beep-beep-beep" when all the "sand" has moved to the bottom piece (timer done).

Extra task: $10 bonus if you can get it to run on an Atmega 8 (I tried a few boards available online but it seems to work on the 328p / Uno only).

Feel free to ask any questions. Serious bidders only please.
