Should have put a trailer the other time

I thought I was going to end this game pretty quickly, but MY BRAIN HURTS. The puzzles can get incredibly tricky, and guess what, I found out there are eight hidden stars in the game which the game doesn't even tell you about, and you can play through the entire game and never discover them. If you do discover the stars though, then collecting all eight hidden stars in the game rewards you with an alternate ending.

Except, even after watching the solution to getting all eight stars, I have no intention of trying to get them. I have no clue how in the world did anyone even figure out how to get the stars themselves without any help because I think my brain cells would have been fried before I could get there.
