it works on stuido and game but only the local player.how do i fix?

this is a local script in starter pack

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local we = false

mouse.KeyDown:Connect(function(key) -- lol i tryed keyheld ;-;
    key = key:lower()
    if key == "q" then
    if we == false then

        local x = Instance.new("Part",workspace)
        x.Shape = "Ball"
        x.BrickColor = BrickColor.new("Cyan") 
        x.Transparency = .5
        x.BottomSurface = "Smooth"
        x.TopSurface = "Smooth"
        x.CanCollide = false
        x.Anchored = false
        x.CFrame = player.Character.LowerTorso.CFrame * CFrame.new(0,0,-6)
        local v = Instance.new("BodyVelocity",x)
        v.Velocity = player.Character.Head.CFrame.lookVector * 90 --mouse.Hit.lookVector* 90
        v.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
        local clone = game.Lighting.water:Clone()
        clone.Parent = x
    x.Name = "flame"

        local boo = script.Parent.dmg.water:Clone()
            boo.Disabled = false
        boo.Parent = x
        wait(2)
    x:Remove()
    end
        end
    end)
