I just downloaded a fresh copy from itch, uploaded on the Panic website and it worked fine.
Not sure why it was failing before. I had seen the error twice when attempting to load to website.
so, I just did the latest system update, then launched the game and loaded Spooky World level 2. When I got to the first vertical moving platform, I jumped left and grabbed the key, then I was unable to jump again. I’ve seen this behavior a handful of times before on the platforms, but I thought I’d let you know since it was in a session from a clean system reboot and on my first try.
