galois binary package in Ubuntu Focal armhf

 Galois is a computer game of the "falling blocks" type, but with
 unique features. Unlike most other games of that type, it is not
 limited to blocks made of four two-dimensional, square bricks: you
 can choose among several different brick shapes, blocks composed of
 more or fewer bricks, and even between two- and three-dimensional
 games.
