In this beta version of the game, you pilote a spaceship in middle of meteorites and alien spaceships. You have to explode as many as possible to gain points. Your score is shown on the right of the screen. Above it, the vertical coloured bar shows your life level that will reduce as more and more meteorites and ennemy's shoots hit you. On the right side of the life bar, your ship is shown in black. When your life level is close to zero, it will blink red to alert you. To start the game, click on your ship that will be directly linked to the mouse. You can then drive him by moving the mouse and shoot by clicking the left button. Good luck...
If you want to play this game offline and without any browsers after December 2020, then download .swf game file and use any Flash Player that runs .swf files.
For Windows users, I recommend ARFlashPlayer (it supports fullscreen option) or official Adobe Flash Player. Both programs are portable.
Another way to play flash games is to install SuperNova SWF Extension (it works in Chrome only).
