I made this little guy intending to make an entire pen based shooting game, but then I realized... I suck at programming. So here we are! Anyone feel free to make an actual game out of this. You could probably make enemies using the player making code and changing the color. You will however need to make it point towards the player instead of the mouse. Song is (I think) Red Dead Redemption 1 Theme.
