Terrible game.

No instructions, no controls, and all we're given is the obvious fact that this is a shooter game, And I'm not even sure how it is two player when there is only 1 ship in the game which we are playing as.

Uhmm... theres only 1 enemy , no further areas, no music or soundeffects at all.

A good start. I would suggest you add some basic instructions at the start and maybe a score counter for each player.

Please don't submit tests. No one wants to play that isn't finished.
