Kliktopia: Land of the Freeware
Made using Multimedia Fusion 1.5 (build 119).
SmileyHouse was a fun and quirky MMORPG made in Multimedia Fusion using MooClick that was active between 2002 and 2008 where everyone had their own customisable smiley.
The official SmileyHouse server is currently being hosted by Kliktopia, so people can play the game just as it was.
All of the old accounts have been preserved, but all passwords have been deleted for security reasons so you will need to ask on the SmileyHouse Discord to get access to your old account.
If you want to find others to play online Klik games with then try asking in the #klik-online-gaming section of the Kliktopia Discord server (and for SmileyHouse you can also try the SmileyHouse Discord).
To get a sense of what the game was like you can check out the SmileyHouse 2019 Reunion photo gallery.
