Suggestions:
Dont paste #define CVAR_FLAGS into it if youre not gonna use them
Add the voluntary release CVAR to be enabled by this plugin.
Im curious as to how this works ingame. So you set the Smokers MOVETYPE to the ghost kind and half speed. Does this mean he accelerates like in ghost state (only half speed)? And what about the victim, does he get a speed boost too or gets dragged to you with constant velocity? Can you 'run off' with someone? What happens when the victim reaches you?
