AstroSalvor - 2D arcade flight with physics Thread

Hello!
Please take a look at my new game AstroSalvor. It is an browser and Android arcade space flight with old-style graphics. Gameplay is based on physics. Your goal is to drive your spaceship and save astronauts calling for your help. Crashes into walls and alien creatures are fatal. Becareful - the moving up speed is reduced only by gravity. Where are no way to slow it manualy. Time you have to save each astronaut is limited and reduced from level to level.

Please check my game and let me know do you think it is interesting and what to be improved?
