Thank you very much for taking the time to go through the game and the detailed feedback you gave. I am not a native English speaker and this feedback was of great value. Much appreciated. I have updated the game and re-uploaded it.
For the link at the end, that is already possible with the current version of Adventuron. You can type in the following to get a hyperlink in your game:
