mu-cade 0.11.dfsg1-12build4.1 (arm64 binary) in ubuntu focal

 Mu-cade is another shoot-em-up game by Kenta Cho. In this game Kenta has
 introduced physics into his formula of hardcore shooting games. Similar
 in some ways to Asteroids and Nibbles, the playing area is a rectangular
 arena in which vessel-snakes have only one idea at the head: expelling
 the others into the vacuum. You incarnate one of them, and you'll quickly
 realize the subtlety of the goal: your tail lengthens as you destroy your
 enemies.
