I have now completed Traffic Jam (find it in Python strategy games)
I have finally managed to link all my programs with a menu (trinket.io/python3/df7b99779e?runOption=console) to work. To make this work I needed to make another program.
I have now competed my lily pad game (see it here: Python arcade games). The hardest bit was getting the frog to move at the same speed as the lily pad it was on. It confused me because you can't get a return from the update function (explained in flappy-bird-done.html), so I used a global variable to report the speed of the lily pad.
