The ArmorGames website is currently in an ongoing state of updating/enhancing. There was a Beta test back in 2011 and a lot of features and possible upgrades were tested in that period. Right now, the web dev team is graduately introducing new features, Quests being one of the biggest new implemented upgrades to the website. =)
If you have more questions for your project, please feel free to email Ferret (ferret@armorgames.com) and he might be able to answer any other questions you may have, ok?
