I'm having a contradiction with a friend about the health bar in a game.
He designed it so that the hearts are getting empty (greyed out) from left to right, and I said to him that they should empty (as you lose life) from right to left.
My argument was that most of (if not all) the games are designed this way, and his argument was that he wanted it to be different.
My question is, it is better to keep it consistent so the users would be already accustomed with it, and not get them confused, or make it different so it would be more interesting?
Edit: The health bar, in my case, is actually some inline hearts, and are placed in the middle, and it's the only health bar in the UI at any point.
