I'm hoping someone can help me, and I will be ultra mega super grateful to anyone who can!

I just started playing Lamento and things have been going fine, but I've reached a part that I can't get past. I don't know if I would call it "freezing", since the menu and toggle text keys still work and I can save and load, but the game won't progress with the left mouse click or enter key. Here's a screen shot of it:

has anyone else struggled with this? I've tried restarting the game a bunch of times but it's still stuck

thank you for taking the time to read this!
