Run, jump and attack! Every step could be your last, how many lives will you be able to take this time? Prove that you are worthy of being called a ronin.
Click on the screen (or left mouse button) to jump and... that's it. Yes, it's that simple! Avoid cyborgs, they are immortal and will not leave you a chance (and in general, beware of everything blue). The more enemies you destroy and the further you run, the higher your score.
