Astra - 1.0.1

Astra is a game where you have to move planets from their origin to their destination. To do so you control one planet whose mass you can increase or decrease in order to use gravitation to attract the other planets.

Astra is a game begun for Novendiales 2006 game compo. Theme was gravitation. As the game wasn't finished at the end of the contest I've continued adding missing features. Goal is quite simple: according to gravitation objects attract each others in function of the product of their mass divided by the distance between them. In Astra you move the gray planet and use gravitation to move the other planets from their starting position to their destination. Default keys are the arrow keys, E key to increase your mass, R key to decrease it. A level end whenever there is no planet to move anymore. If all the planets are placed then you go directly to the next level. If some planets exploded then you can retry the current level to improve your score. You score points for each planet correctly placed and get a bonus if all the planets are placed. At the beginning of the game you have 3 lifes. If you lost all of them and decide to continue then your resurrection will cost you some points. 10 levels are available. You can either use keyboard, joystick or mouse (gameplay is better using keyboard or joystick). UI can be switched into English or French.
