This game uses several different types of genetic inheritance to breed generations of pets. There are lots of user run contest and guilds that are focused on different things - some on breeding certain designs and others just for like-minded folks. There are lots of things to do, especially for self-driven users. Importantly the staff listen to the users and are always using their ideas and suggestions to help improve the game and the user experience. 

Most of the art is absolutely amazing. I think some of the mutations are a bit awkward on some breeds in my opinion but I think this is just personal taste. The amount of smaller pieces of art made just for promotion or events is astonishing. The variation in item artwork is great. Updated line arts for the different breeds are also very refreshing.

There's lots of different mini stories that go along with each event, as well as site-wide canon and lore.

The community is excellent. I'm one of the arbiters for The Flood Club (Ruthless ID# 147803) and I have been welcomed openly both into that guild and various other clubs and guilds across the site. 

It's great! There's lots of updates to mechanics, items, and the markings and mutations.

The staff are very approachable and always willing to help out or point you in the right direction. This can be anything from site issues to wanting to breed with their wajas/pets.
