This is more trouble than it is worth, eh. xD
I was just saying that you shouldn't multiply the amount of steps you get on one floor (if you can judge how many make a floor when going up the staircase?) by 59. You'll have to work it out by noting how many steps there are on one screen then multiplying it by the amount of screens there are to get the total number. I need to play to check the actual answer.

(Unless the amount of steps per screen are different each time, but if this was the case then the question is stupid.)
