This is a project to be done fully in java/java fx. It is a space shooting 2D game. The freelancer should be able to create wonderful 2D backgrounds and sprites. The game should have at least 5 levels (increasing difficulty). The game should be responsive (multiple threads to handle graphics and game logic). Other details regarding score system, enemies, lives, bonus, animations, and others will be discussed if needed. This is a challenging task but doable.
I need the project be done in the shortest time possible.
