Since the original watchface is NOT open source, this "port" could be more accurately described as a recreation based on assets dumped from the original.

Differences From The Original

Re-scaled to look better on the larger displays of the Pebble Time/Round 2
Some of the extra screen space is used to display the date and Bluetooth status
Original creature part modifications
- Some creature parts that resulted in broken-looking creatures were overhauled
- Any creature parts that previously had cut-off details to fit on the smaller display have been extended
- Some creature parts removed by the original developer (to conserve space) have been re-added
- Most creature parts now have manually placed accent colors
Creature parts are now dynamically and randomly re-colored when loaded in
When swapping, creature parts now enter on the opposite side they exit from
This port is not compatible with black&white Pebbles
- The original Maan On My Wrist is still perfectly silly on b&w screens!

Considerations For The Future

Add more Maan art (see this gallery for potential candidates)
Potential light mode (don't hold your breath - I'm still not sure this would look good and I don't like the idea of having settings)
Black&white support if I get bored or Pebble releases a modern b&w watch (Flint doesn't count)
