Thank you for playing, Woben.
Ah, yes - the problem is that the image is blocking the map... And I commented out the listener on the image which removes the image. :X I have fixed the issue and will update the game after the jam voting period.
You can restart the game and chose to go to the tram stop (the yellow paint) - that is another branch in the story. There you have another conversation.
I look forward to reading your impression of the way the dialog works.
