Hi there! I’m really sorry, but unfortunately these are two unrelated issues, and neither of them has anything to do with the code, which is correct. Other creators are also experiencing the error with CoGDemos, while the one on itch.io—I’m not sure what’s causing it, but I see at least one other person has run into it too (and just yesterday, too!). Could you please try again using a different browser or device? I’m really sorry for the trouble you’re having.
