Honest opinion: This kind of has the problem of the Petscop playable version where actually playing it kind of reveals how artifical and empty it is, because it's not meant to be played, it's meant to tell a horror story. That said, still very cool to have a playable version--I was just kind of hoping it wouldn't be literally the same thing as the videos.
While I haven't seen much yet, I can safely say this: after deliberately hopping into one of the secret areas at the start, it certainly doesn't seem to be exactly the same. There's actually something new here...
But yeah, we can't expect this to suddenly start playing like a Banjo Kazooie game or anything, as much as I'd love to see some collectathon elements fully realized here 😅
