Programming education game with SenseHAT

So, again I made a game, so I will post it. It's getting fun.

I made a popular programming education game for children recently. That is to instruct (program) the route to move to the specified location. Move from orange to blue. However, if you just move it, it will be in a straight line vertically and horizontally, so I also added an obstacle (green).

I'm not using an event handler because this is a completely sequential process. However, it may be an ant to move by inertia.

For the time being, my elementary school daughter liked it. Yokatta. It has not been verified whether programming learning can be done with this. ..
