 # TODO
 A list of things I'd like to accomplish
 
-* Game loop
-* Create and load worlds
+## In Progress
 * Daemonise the serverside
 * Expose a socket or pipe on the daemon for the client
-* Client connection to daemon
+* Create client to connect to daemon
+
+## Completed
+* Split into client and server (and common library?)
+* Write Makefile to automate compilation
+
+## Planned
+* Game loop
+* Create and load worlds
 * Display environment and pan camera
 * Time controls (play/pause/speed up)
 * See creature stats
