It would have been nice to have feedback for when its our turn to pick/refuse card, i have no clue so i end up spamming left/right click. It works but not elegant :)
i dont really like the white and black square for the draw pile and gun, you could have extremly easily replace them by card/gun icon at least, same for the opponent, a simple whatever icon would have worked fine :)
and some ambiance music and lighting would help a lot for this kind of backround bar setting :)
Its a nice littel prototype, keep on going :)
