So, I have a game I am outputting to glulxe, and I am trying to run it in Quixe. I notice theres some things not supported, such as right-aligned text.
Is there a list of stuff I should avoid in a glulxe game to maintain parity between Quixe and other runners?
I’m afraid there is no list. If there were, the big entries would be graphics, sound, paragraph styles (as you noted), and adjusting styles from within game code. (You can adjust them in the CSS file.)
All of these things are on the to-do list, but the list has been hovering for years. I tender the usual apologies. This year I made a lot of progress on the iOS interface, not so much on the Javascript one.
