I have uploaded my new game with C2 'running grey' it is a one button scrolling platformer. It is horribly simplistic at the moment since I am no great artist and have done what I can.
Not sure if its been validated yet or not on the arcade so you can also play it on my own server. But have a play, I intend to add a lot more to the game over the next couple of weeks, once the game is in a fit state I will update the graphics and animation as well to look nicer.
P.c. the difficulty increases as you run faster.
