How to add coins and powers to my game?(and that if you leave 4 glass walls you get coins for it

Please tell me what scripts u need if that here is not enough.

-replicated storage -ball -click detector -script:

local c = script.Parent local b = c.Parent

function Destroy() b:Destroy() end

c.MouseClick:Connect(Destroy)

-,,Generator" (round part) -script:

local r = game.ReplicatedStorage local b = r:WaitForChild("Ball") local g = script.Parent

local n local s local c local x local y

function Generate()

n = b:Clone()

s=math.random(4,40)
n.Size = Vector3.new(s,s,s)
x = math.random(-10,10)
y = math.random(-10,10)
n.Position = g.Position + Vector3.new(x,0,y)
n.Parent = g
n.BrickColor = BrickColor.random()

wait (0.2)

end

while true do

c = 100 

wait(10)

print("New Game!")

for i = 1, 40,1 do 
    Generate()
end
for i = 1, 100,1 do 
    Generate()
    wait(1)
    c = c - 1
    print ("Pozosta?o"..c.."s")
end
print ("Time ended!")

g:ClearAllChildren()
end
