Congratulations!
I had a brief look at this on mobile but unfortunately it's rendering in landscape mode (Itch requires that you select landscape or portrait).
Please see steps 9E, 9F, 9G at the following link to see how to configure this:

Another point is that the intro text might be better using the : stagger command instead of the : print command. This is just like a print but it controls the flow of text paragraph by paragraph so that the text doesn't flow off the screen and it focuses the player on seeing content one chunk at a time. Good to test on mobile.
I'll take a bit more of a look at the game itself a bit later. Kind of busy on responding to various issues today.
