Tentang Proyek
Ini adalah game sederhana menggunakan MAX72XX LED-Matrix sebagai tampilan, dua tombol mikro sebagai tombol dan buzzer aktif untuk efek suara.
Anda adalah kapal angkasa dan Anda harus menghindari kontak dengan asteroid yang jatuh ke bawah. Game semakin cepat seiring waktu. Di akhir, skor ditampilkan yang menunjukkan berapa lama Anda bertahan.
