While your mouse was hovering over the track it was an icon of a race car.
I used 4 different icons so that the car was pointing in the right direction as you moved around the track.
If you moved out of bounds you lost.
To be honest I didn't even know that it was "programming" as far as I was concerned Hypercard was just another app I was using like paint etc.
In retrospect it was very intuitive and might be the best version of "zero code" I have seen to date!
