I'd rather use set_user_rendering( ) and get/set_user_maxspeed( ) from Fun module instead of using FakeMeta for that. And about ResetHUD, if you are trying to hook the spawn you should use HamSandwich instead.
Also you shouldn't bind the key to the players ( slowhacking stuff is not allowed here ), let them bind the key they want, but add a print to tell that.
Finally, you should attach the plugin here instead of linking it.
And I think that's all from me
