I've been thinking of some things that should be added to Kart Kingdom. Here are a few suggestions I have.

Trading/Gifting System

More secure password security

Free Chat (Except there are some words you can't type, like on Animal Jam)

A house (garage?)

Shops and more lands, and some form of currency

Pets and adoption centers

More quests

Items that can expire except for code items, maybe special exclusive shop items so that trading will be more vital
