overview

basicly one moves around with keyboard and interacts with mouse. a context based pop-up menu appears with right click. mouse cursor changes to indicate interactable objects (such as users)

camera can be can adjusted as first or third person

while talking cartoon style balloons appear over avatars. talking comes in three flavours: whisper, normal and shout. in whisper mode only the users you whisper, in normal mode only the users close enough, in shout mode all users will hear you

at least for now karga is unmoderated. if you are disturbed by someone right click over him/her and select 'dont see xxx'. after then you wont see each other

well this is it at a glance, now go on and have fun ;)
