Anything but a "Reset Data" button in the Settings 🥀 (no seriously I went into RegistryEditor under LukeGames, changed value of "Sally" from 1 to 0, even deleted all the keys and Scary Mode won't come back)
Ok but besides that bit of feedback I felt like the Scary Stuff was just alright. While I liked the ambience of Scary Mode there wasn't much tension in terms of gameplay as keeping away from Blind Baldi is easy if you're patient and the ending jumpscare is pretty much an expectation at this point. Maybe if more was done with other characters like the eyeless Anim8or bird it would be more interesting but as it stands it's just a simple stealth section in the dark with most of the challenge coming from remembering where your keys and last notebooks are.
Also, the audio/visuals of the cutscenes seem to just be there for shock value (most notably the flashy red swirl which pops up three separate times), although I'm not too familiar with the creepypasta behind this mod (no habla español) so I can't really judge.
However and as others have said, I quite enjoyed this mod for bringing me back to the early days of BBiEaL decompiling where adding a few extra rooms, BSODAs, and Pencil Boy made you the best modder ever lmao
