Help with a noob project

[UPDATE: Problem Solved]

(Apologies for cross-posting)

Hi, kind people.

I’m working my way through an online introductory course to Game Design and I need your help.

For one project, we were asked to use some standard and custom assets (that the teacher provided). I follow everything closely but when I want to enter the play mode, I get a compiler error about two of the custom scripts. I was wondering if anyone can take a look at the project and let me know how I can fix it. I asked the teacher about it but I don’t think he’s ever going to answer!

This the link for the project:

This is the error: Assets/Scripts/TriggerLevelLoad.cs(3,19): error CS0234: The type or namespace name SceneManagement' does not exist in the namespace UnityEngine’. Are you missing an assembly reference?

Btw, I’m using Unity Editor 5.1.2.

Thanks.

The class SceneManagement is only available from the unity version 5.3 and newer.
