You're allowed to save array's in dataStores, you're just not allowed to save Userdata.

The only things that can be in the array that you save are strings, numbers, and booleans.

You'd have to save your stuff like this:

Data = {
	Level = Level.Value,
	HairColor = {
		HairColorValue.Value.r,
		HairColorValue.Value.g,
		HairColorValue.Value.b
	}
	--etc
}

For loading we can then index it like so:

local level = Data[1]
local HairColor = Color3.new(Data[2][1],Data[2][2],Data[2][3]) -- or fromRGB. Not sure.
--etc

Any questions? Post a comment below ;)
