Can you lead me in creating rpg game like?

I have done the leader boards already

local level = 1
local exp = 0
local axp = 20

local InStudio = game:GetService("RunService"):IsStudio()

if not InStudio then
	level = game:GetService("DataStoreService"):GetDataStore("Levels")
	exp = game:GetService("DataStoreService"):GetDataStore("EXP")
	axp = game:GetService("DataStoreService"):GetDataStore("AXP") -- Amount of exp needed to level up.
end

function savedata(dataname, playerid, value)
	if InStudio then return end
	dataname:SetAsync(playerid, value)
end

game.Players.PlayerAdded:connect(function(player)
	local leader = Instance.new("Folder")
	leader.Name = "leaderstats"
	leader.Parent = player
	local levelz = Instance.new("IntValue")
	levelz.Name = "Level"
	local xpz = Instance.new("NumberValue")
	xpz.Name = "Exp"
	local xpn = Instance.new("IntValue")
	xpn.Name = "ExpNeeded"
	
	if not InStudio then
		xpn.Value = axp:GetAsync(tostring(player.userId)) or 20
		xpz.Value = exp:GetAsync(tostring(player.userId)) or 0
		levelz.Value = level:GetAsync(tostring(player.userId)) or 1
	else
		xpn.Value = axp
		xpz.Value = exp
		levelz.Value = level
	end
	
	levelz.Parent = leader
	xpz.Parent = leader
	xpn.Parent = leader
	
	xpz.Changed:connect(function()
		if player.leaderstats:WaitForChild("Exp").Value >= player.leaderstats:WaitForChild("ExpNeeded").Value then
			levelz.Value = levelz.Value + 1
			
		
			
			xpn.Value = math.floor(xpn.Value * 2) --You can change this if you want.
			xpz.Value = 0	
			
			savedata(level, player.userId, levelz.Value)
			savedata(exp, player.userId, xpz.Value)
			savedata(axp, player.userId, xpn.Value)
		else
			savedata(level, player.userId, levelz.Value)
			savedata(exp, player.userId, xpz.Value)
			savedata(axp, player.userId, xpn.Value)
		end
		savedata(level, player.userId, levelz.Value)
		savedata(exp, player.userId, xpz.Value)
		savedata(axp, player.userId, xpn.Value)
	end)
end)

game.Players.PlayerRemoving:connect(function(player)
	savedata(level, player.userId, player.leaderstats.Level.Value)
	savedata(exp, player.userId, player.leaderstats.Exp.Value)
	savedata(axp, player.userId, player.leaderstats.ExpNeeded.Value)
end)

--Animation Script (Local Script)
local player = game.Players.LocalPlayer
local exp = player:WaitForChild("leaderstats"):WaitForChild("Exp")
local axp = player:WaitForChild("leaderstats"):WaitForChild("ExpNeeded")

while true do
	wait()
	local expBarSize = (exp.Value/axp.Value) - 0.02
	if exp.Value == 0 then
		expBarSize = 0
		script.Parent:TweenSize(UDim2.new(expBarSize, 0, 0, 20), "Out", "Quad", 0.25)
	else
		script.Parent:TweenSize(UDim2.new(expBarSize, 0, 0, 20), "Out", "Quad", 0.25)
	end
end

--ExpText Script (Local Script)
local player = game.Players.LocalPlayer
local exp = player:WaitForChild("leaderstats"):WaitForChild("Exp")
local axp = player:WaitForChild("leaderstats"):WaitForChild("ExpNeeded")

while true do
	wait()
	script.Parent.Text = "EXP: " .. exp.Value .. "/" .. axp.Value 
end

--GetLevel Script (Local Script)
local player = game.Players.LocalPlayer
local level = player:WaitForChild("leaderstats"):WaitForChild("Level")

script.Parent.Text = "Current Level: " .. level.Value

level.Changed:Connect(function(value)
	script.Parent.Text = "Current Level: " .. value
end)

--GiveExp Script (Server Script)
local PlayersService = game:GetService("Players")

local function onTouch(hit)
	local player = PlayersService:GetPlayerFromCharacter(hit.Parent)
	local expPoints = player:findFirstChild("leaderstats")
	if expPoints ~= nil then
		local points = expPoints:findFirstChild("Exp")
		if points ~= nil then
			points.Value = points.Value + 5
		end
	end
end

script.Parent.Touched:connect(onTouch)

i want wooden dummy to give the amount of exp when died (like in rpg game :D)

The answer will be in 1-2 hours
