The main menu looks great and the red colours on black are really striking especially with the smooth punching animation. I was also impressed by the range of settings available and I selected full screen as suggested. However, for me on my computer, the actual game didn't work so well. The movement was laggy and the interesting flickering effect just made the game difficult to focus on. Adding to this half the screen got blocked out by a strength statistic graph thing and made the game unplayable. I would recommend testing the game on different set-ups and browsers and possibly adopting the colour scheme from the menu (red and black). I hope that's useful.
