Final product

Challenged with the final product

・ Soccer PK game ・ Amidakuji etc ... However, ...

I gave up because I couldn't make it with my own ability. I reconsidered and came up with

** Break the block with three balls **

#Summary By doing this, you can break the blocks by turning all the balls, triangles, and squares in the lesson into balls, and then programming the blocks to break. I will try again the soccer pk game and Amidakuji that I couldn't do.
