I decided to jump back into the game and managed to get all 4 boxes to the end. I had to try it myself since I noticed a lot of people talking about getting all 4 boxes to the end. It wasn't as hard as I expected it to be, but I did glitch one of the boxes out of the map followed by me glitching out of the map on my first attempt off screen. That wasn't supposed to happen...
meet the bad ending, i call it the: 'lost within nothing' ending, here's the link to the video
