This game was just your usual space shooter with a very dispassionate dressing. The gameplay itself is hardly interesting. Making a game requires more than just a theme and graphics.
This game is really awesome. I wasted a lot of time, but it's still awesome. One thing I'd suggest you add, is the ability to do straight lines, and also a feature where you can add lettering. I also really like the sharing thing about it. Keep up the good work.
