If you want some extreme running but you don't wish to break any bone then we have The Gauntlet for you. You are going to control a stick guy who is trying to run away from the emptiness of a virtual world. The tutorial shows all what you need. You have only three chances to make mistake. It's not too much but with a bit practice it should be ok. The later levels, the difficulty is really high but it's so catchy you will try to beat your best score many times.
