Well, the TLDR goes at the beginning of the comment, not at the end. You made a Postscript.
The game tells you exactly what to do. You don't need anything more than to read and follow the signage that lights up in the text box, which fulfilled your point 1. In addition, it uses the color red, which is universally used for engage in all types of turn-based games.
Perhaps it could be inside an entirely colored box, as if it were a button, but it would lose the minimalist, cyberpunk artistic design.
P. S.: Hey, I didn't make the game, I'm just someone who is playing it.
