Press space to spin, up arrow to jump. Press the left and right arrows to move. Use the a key to switch backdrops. Ignore the kicks bit. I'm starting on a ball game part. Just be patient about it. Press b to kick the ball, c to make the cat drink, and d to make the cat eat. Remember: watch the health! Otherwise you might die. Press 0 to hide the variables (that includes health, so watch out). If you didn't convert, press 1 to show variables, and if you did, press 2.
The miles is approximate. 528 steps=0.09995 miles, not 0.1, but it is very close. I did it with a calculator (well, my mom did). Kilometers are exact. 1000 big steps= 1 kilometer. Thanks to ScratchaGotchi for the idea. 1-15-15: added kilometers, game shared
