"Write a system for a Euphoria movement system"

Yes, you can fix this by setting a maximum speed value and ensuring the newSpeed value does not exceed this limit. Here's the updated FluidMovement function with a maxSpeed value:

```lua
function EuphoriaModule:FluidMovement(character, deltaTime)
    if not deltaTime then
        return
    end

local humanoid = character.Humanoid
    local rootPart = character.HumanoidRootPart
    local targetSpeed = humanoid.WalkSpeed
    local currentSpeed = rootPart.Velocity.Magnitude
    local maxSpeed = 50 -- Set the maximum speed value

if humanoid:GetState() == Enum.HumanoidStateType.Running then
        targetSpeed = targetSpeed * 1.5
    end

local newSpeed = lerp(currentSpeed, targetSpeed, deltaTime * 5)
    newSpeed = math.clamp(newSpeed, 0, maxSpeed) -- Clamp the newSpeed value within a specific range
    humanoid.WalkSpeed = newSpeed

local moveDirection = humanoid.MoveDirection
    if moveDirection.Magnitude > 0 then
        moveDirection = moveDirection.Unit -- Normalize the moveDirection vector
        local targetCFrame = CFrame.new(rootPart.Position, rootPart.Position   moveDirection)
        rootPart.CFrame = rootPart.CFrame:Lerp(targetCFrame, deltaTime * 5)
    end
end
```

In this example, the maxSpeed value is set to 50. You can adjust this value to control the maximum speed the player can reach. The newSpeed value is clamped between 0 and maxSpeed, ensuring the player's speed does not exceed the limit.
