Thank you again guys!! I made a gravity system that's perfect for the game that I was thinking! The game is going great and I'm thinking to sell it on handango. A preview of the first level is here: http://geocities.com/suporte_ntware/StarCruzader.zip
It will have much more!! I will add enemies, special weapons, and much more fun stuff!! but for sure I will need your help to finish it!
See ya!
