Star War 2 Battle

This is a shooting game in space. You have to destroy the enemy's spaceships, depending on the settings you choose, 20, 40 or 60 ships.
You can move forward, backward, left and right with the arrow keys. Then you can use accelerations to get closer to the opponent faster. There are 5 turbos and if you buy more turbos, you get a total of 105 accelerations per game.
On the left are 5 buttons: forward, backward, left, right and stop.
On the right are 3 buttons: shooting, turbo on and turbo off.
Either you or they can win.
