There are many ways to connect to the Cleft of Dimensions!
The game is accessible via telnet at cleftofdimensions.net, port 4354.
Our custom client is Project Tuna. It has a custom GUI with output split into several windows for your convenience.
There is also a GUI package available for Mudlet which replicates the Project Tuna experience. This package will download automatically when you connect, but can be downloaded manually from https://www.cleftofdimensions.net/clients/cleftofdimensions.mpackage
