Simple 1-Level Gamesalad Game

Hi Everybody. I am working on a gamesald project and I require a freelancer to build the game level scene. I have all artwork ready to insert into the game. Here is the project info: It is a single level shooting game where you can either shoot left or right by touching on the left or the right of the screen. There is no end to the game The score just gets higher. Enemies spawn randomly from either side of the screen, increasing in speed as the time increases The backgrond of the game is fixed, (non-scrolling backgound) I would like to release the game to IOS, Android and HTML platforms using gamesalad. This is a brief rundown of the game. contact me for more information.
