Play with a friend, your own best friend, a random player, but just remember, teamwork makes the dream work!
I would also like to say that in the part where it has grey blocks everywhere, DO NOT PRESS ANYTHING OR DO NOT PRESS F TO USE and wait for your teammate to press the green button. If you do press f or use, then you have to join the game again with your teammate and do the part again. If you are that teammate, then I would rather tell you to press the green button for the other teammate
