Hello! There is some work to do. :)
0)this is a fan-made Sciarra's BANG! readaptation? https://en.wikipedia.org/wiki/Bang!_(card_game) As a good practice, I think they should be acknowledged
1)It does not work with Firefox. I used Chrome to run the single-player mode.
2)Intro needs a CONTINUE and a SKIP button. It is frustrating I can't go forward, and it is twice as frustrating when I misclick "story". Btw. enjoyed the background you gave to justify why people do not know each other.
3)Game shall start after I close the "play rule". Too much information on the screen, it is a mess and I do not see the central character.
4)Characters' ability should be in-game available.
5)Characters' moves should be on-screen visible (not just text).
Best!
