There is network support with several multiplayer options and user extension with Scheme (via Guile) to program the little ship to do some things automatically are in the works.
tenmado is a vertically scrolling, late 1990s style (i.e., 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.
