I like the 8-bit rendition of FNAF. Fun to see the control room, the UI, the cameras, and the sounds effects in a retro-ified style. I think they work well for what you set out to do.
I've never played any FNAF game, but I just barely made it through the first night, with less than 5% power remaining, and Bonnie staying visible through the left window for a while which was scary! I can't speak to the gameplay since it's not my thing, felt slow paced. I do wish there was a "you are here" dot on the map for people who haven't played FNAF before; I noticed in the AI video you linked, there was one.
