Space trophy is a game where you can control your spaceship only with left mouse button (like Copter and Metro Syberia games). Hold left mouse button to fly higher and release it to fly down. There are two game modes.
1. Story mode (press "Play" button in main menu)
You have to complete 7 levels to win the game. Collect fuel to fly and stars to upgrade your ship. When you gain more than 5 stars, upgrade screen will appear between levels.
2. Survival mode (press "Survival" button in main menu)
Fly as long as you can and post your score.
Hold left mouse button to fly higher and release it to fly down.
