This game has 5 missable trophies (well, 6 if you count this platinum
). This guide gives the minimum amount of spoilers required for you to complete the game with all achievements but without the full step-by-step walkthrough.
After you wake up, click on a photograph above your bed.
When you are in your Mom's bedroom, look at the photograph on the mirror and unfold it.
When driving your car, use different tapes for two journeys so that you've used both available tapes. You'll need to get back in your car after agreeing to do a favour for Jesse in order to trigger a second journey that allows you to use a tape (Also needed for The Past: Four below).
After agreeing to help Jesse, leave in your car and knock on the door then get back in your car to go back to the school.
When you enter the Boys' locker room, use the Mirror.
You should have two remaining achievements at this point that will unlock as you complete the game.
