Just gonna say off the bat, I wish the controls felt more consistent with the turning and stepping.
Now, to have that out of the way.
MY GOODNESS THIS GAME IS SO COOL!! You have a working highscore system, the mechanics and usage of the theme was extremely creative, and the challenge of being careful not just in the game, but in your actual movements in real life. By far the most creative of the games. The idea of being careful, but then having to watch the timer and having enemies which can move and hit you later on does seem a bit counter-productive, but that's only really because of my main complaint making it worse than it really was meant to be. Besides these, I should point out the red flashing when losing life seemed a bit too 'epilepsy warning' levels of flashing.
