I did try to interact with the lamp post, but it did not work. I have now tried the game again, and after pursing the E-button 10-15 times it worked. I also have the same issue with text boxes.
Yeah...i dont blame you, it is tricky to get it, even for me. I didnt got time to upload the version of it where it worked. But if you really want to, i can provide a link to a working version.
