Currently making a remake of Geometry Wars. I first make it with Slick and I just port it to Java2D (OpenGL problem…). I would like to know how it runs for you.
Love it and love twin stick shooters. One suggestion, make the lines of your game objects thinner to look more like vector drawn. Thick lines look “flash like” to me
Runs nicely, very smooth. One suggestion is maybe put an distinctly coloured image where the cursor is, with a lot of sprites on the screen its hard to see where you are aiming. And of course the GUI/Buttons are ugly but am sure you are aware of that
I (strongly) suggest always keeping the player ship in the center of the screen, or your aim changes from moving around and not only from moving the mouse.
