Just played it, I'm assuming the end of the demo is where the loading screen is cause it seemed to be stuck there lol.
I definitely did have bad slowdown throughout but I tried to push past it, it's a very cute and charming experience when it is running properly. I was always curious what would happen when Pappah grabbed you so I got my answer.
Excited to see it fully complete and I'm glad I could get a bite-size experience of it!
