I had always only the three answers "?", "!" and "..." available and also got stuck in the second dialogue. But I thought charlie was hilarious.
Sorry you got stuck :/ What exactly happened before you got stuck? Did it freeze? Did you get caught in a loop you couldn’t progress past?
And only having those three answers was an intentional choice :)
The Game was running normally but there was nothing to do for me. There were no interactions to click in.
I just tried and I see what you mean. It’s a bug, sorry :(
I replayed it today and this time the bug didn't occur. Except for that well executed game.
