and this is the script i have:

ACTION:

LUA: 
function onUse(cid, item, frompos, item2, topos)
	if not isPlayer(getGlobalStorageValue(SNAKE.freeglobalstorage)) then
		doTeleportThing(cid,SNAKE.controlpos)
		SNAKE.timer(cid,1,nil,item.actionid == 0 and 500 or item.actionid)
		doPlayerSendTextMessage(cid,25,'Aprieta CTRL y mueve las flechas para controlar a la snake.')
		SNAKE.generateFood()
	else
		doPlayerSendTextMessage(cid,25,'Please wait.')
	end
end

Change
LUA: 
controlpos={x=908,y=1190,z=7},
to
LUA: 
controlpos={x=908,y=1190,z=6},
Cuz you are OVER the snake gaming area :=)

EDIT: After install this and test i saw the problem.

You need to change
LUA: 
SNAKE.timer(cid,1,nil,item.actionid == 0 and 500 or item.actionid)
in the action script.. Change the timer

Also i find out that every time the "snake" going to go 1sqm it freezes like 1sec..
BuMp on this if anyone know..
