First time manually walking to the house before the timer expires was fine. I tried it again and I got the black void again. This time I couldn't walk in the darkness and couldn't get the popup box to open up again.
That's what it looks like:
So... super weird, but I tried again on my personal laptop (same browser, Chrome) but didn't have this issue again. I was playing last night on a work computer (DON'T TELL ANYONE!!) so I'm wondering if something was trying to block it from working?
I'll see if I can look into it next time I'm at work, unless Ravery is able to help :)
I also had the same issue. I use firefox for itch games. When I open my web console I do see a few errors pop up that look like they are related to the game. there's a couple more that couldn't fit into the screenshot, but there's several calls on sprites not working, and other stuff like that. I'm not sure what's causing the issue though, since it seems to work on some computers and not others, but hopefully this points you into the right direction.
