Here's the video I found.
It's from @thatawesomefnafremakedev, I think he's teasing Jolly's: Phase 1.

This gives me The Walten Files, Battington VHS, and Squimpus McGrumpus VHS vibes. I think he copied it? IDK. He's still in quarantine. He told me that he's using some kind of a video editor on his phone. He's in a hotel, not at his house. In my opinion, it's well-edited, I guess. The effects, hidden messages ( found like 2 of em), and the idea. I chatted with him about this. He said he's making a VHS series inspired by those FNaF VHS series he saw on YouTube. He named it The Jolly Files. He said that he named it after The Walten Files. It was also for teasing Jolly's: Phase 1's lore. He also said about making a new character for the Phase 2 project we're working on. I know the name, but I'm not spoiling it to you guys. Hehe.

Secret I found:

The "help me jade" message

This was found in the Created by Kevin Johnson text part. This only appears for about 0.4 milliseconds. I asked FNaFDev about this. He said this, "Jade is the main protagonist of Phase 1. The players take the role of Jade, a security guard that can be seen in the starting cutscene being stuffed from a suit. Jade was supposed to be the main character before Mike (current player role when during the night), so that's why I added the help me jade part." This is interesting.

The gray kid face

I found a little gray spot. I decided to brighten up the image. I sent this to FNaFDev and questioned it. He said that it's a kid. It's not clear since the quality is 420p. And he said it's a kid with a J at the start of his name. Hmmmmm.... Jade? This you?
