good job on making a fairly entertaining game for about 3 minutes keep it up just add some things to really make it stand out like maybe some physics multiple buttons to press maybe even a plot as to why he is running a short story maybe? i dont know just feels like its a good base but need to have alot more added in
The gameplay is simplistic, and the fact you have running animation is a good start. A score tracking system might be useful, people love a competitive side to things. The difficulty is far too easy, although for a beginning flash animation, that's not all that important. Keep it up!
