Sorry to hear that! It works on chrome for me! What version are you using? Do you have flash?
Version 52.0.2743.116 m (64-bit)

It did thanks. Your game is awesome. I was trying a timing element for mine as well, but when with something else. What I really like is the Ninja's color transformation as it can have a hidden meaning. Also, did you use flash and actionscripting?
