tenmado binary package in Ubuntu Bionic amd64

 tenmado is a vertically scrolling, late 1990s style (that is, a massive
 number of enemy shots against a smaller-than-it-looks spaceship) shoot 'em
 up game. A very accurate collision detection makes it a game of
 dexterity. If something looks like a triangle, it is a triangle, not
 a rectangle of similar size.
 .
 However, surviving is only 20% of the game. The main feature of tenmado
 is the "color chain bonus". You can get a very big score (about 100 times
 bigger than a normal enemy-destruction point) by destroying enemies of
 the same color successively. It is easy or difficult depending on how
 greedy you are.
