The latest release can be downloaded from etoyoc.com: gilgamesh-v0.0.1alpha.zip
You need at least Tcl 8.6 and the Tcl Sqlite extension to play. Any recent ActiveTcl installation should do.
If you have a Tcl 8.7 interpreter, you can run the game just by either dragging and dropping the archive on your Tcl interpreter executable, or running:
tclsh8.7 gilgamesh-v0.0.1alpha.zip
Otherwise just unzip the contents and either drag main.tcl on your Tcl executable or:
tclsh8.6 ~/gilgamesh-v0.0.1alpha/main.tcl
The game saves to APPDATA/clay/gilgamesh/game.sqlite on Windows and ~/.clay/gilgamesh/game.sqlite in Mac/Linux/Unix. You also have the option to specify a file name:
tclsh8.7 gilgamesh-v0.0.1alpha.zip ~/Documents/My_Gilgamesh.sqlite
or
tclsh8.6 ~/gilgamesh-v0.0.1alpha/main.tcl ~/Documents/My_Gilgamesh.sqlite
Upon starting up the game will open a web server listening for traffic on port 8015. For Windows and Mac users, the game will use the Operating System's "open" mechanism to open a browser window for you. We have a browser hunting scheme for Linux and BSD users that usually works, but if it does not you just have to open your own browser to:
http://localhost:8015
If 8015 is busy, the system will hunt around for an open port.
The game currently opens in a location of "NOWHERE", with no instructions on what to do next. Type "LOOK" in the command line to bring up links from that location to other places.
