Fits Theme: We doesnt see the action, instead, we are commanding everything from the old pc style map.
Fun: Yeah its actually really fun. I feel like this game can sell on steam with more content. Its required to write somewhere all the commands, and its reminds me of morrowind quests (no questlog, write everything by yourself). I am not sure if everyone can enjoy this game as it requires speed typing skills. Perhaps better idea will be to give the ability to write more commands at once, like a script, something like
t2 goto d2
delay 10
d2 open
t2 goto c9
delay 2
d2 close
delay 10
t2 search c9
etc.
