Hey, what a nice concept! It got me to play a few times, trying to beat my highscore :) I was confused at first with the placement of those feet. I thought that if I clicked the left side of the screen the left foot would move and when I clicked the right side - the right would move. But I got used to the way it worked and it turned out to be no difference because you can freely aim your foot without crossing lines. I do believe it would be nice to add some sort of indicator, like making the foot semi transparent when you are in the aim mode. I can see myself playing it on a phone, good job! :)
