I feel like Demon could be even more popular if it used WebSocket. I know such a thing would take quite awhile to implement but the advantages are numerous. Not only could the player play the game on the webiste, but also have people watch their runs! DCCS (Dungeon Crawl Stone Soup) uses this and many people call that game the best "true" dungeon crawler of all time and its players stay connected through the use of WebSocket. If you were able to add this to Demon, it could bring a whole different type of interaction between players besides just using the forum and this could also open up special events on Demon, like tournaments or what-not!
I know this game is fairly new and does not have that many people at the moment but its just a suggestion for the future! (A good one might I add! )
