5# Duel tombol dua pemain. Setiap penekanan mendorong warnamu satu langkah
6# di sepanjang strip; yang pertama mencapai ujung seberang memenangkan
7# ronde, yang pertama mencapai 3 ronde memenangkan pertandingan. Menekan
8# terlalu cepat selama hitung mundur membuatmu kehilangan 2 langkah.

12#   GP14 -> Tombol pemain 1 (RED), kaki lainnya ke GND
13#   GP16 -> Tombol pemain 2 (BLUE), kaki lainnya ke GND
