Sadly, the speech panel disappears behind the environment. I could get through the first conversation because I was able to move away from the house, but the second interaction looked like the game had frozen until I realized that there had to be a conversation going on behind the level graphics. All I could do was blindly press Enter until the character could move again, but without being able to read the conversation, I haven't got the faintest idea what I should do next.
Such a pity, because the story idea sounds very promising and the graphics look beautiful. I'd love to give this game another try after the problem with the hidden UI was solved.
