Needs lots of work.
The graphics were for the most part pretty well done, but that's basically the only good thing I can say about this. Menus seemed to be traps... if Options was clicked, or the Credits link within Options, the game had to be closed to get back to the main menu. Also, the Quit link on the main menu was useless, as it didn't seem to do anything. Dragging the mouse to the very bottom or very right of the screen squashed the display... also, the whole display moved when the ship was moving, which was extremely annoying. There was no instruction, so I had no idea what the heck to do, nor did I know why when I left-clicked a big green box showed up in front of the ship. Furthermore, only one bullet could be fired at a time; if more than one was fired, the first would be cancelled to start the most recent shot. Additionally, the gunfire sound effects in the only level available were HORRIBLY annoying!! Take those out immediately, it's a huge detractor from, well, everything as it's frigging constant. Certain artwork also overlapped others; for example, the big ship covered up the player's gunfire. Your game's title says "Starfighter Beta 3", but the game called itself "Starbomber." Also, the Multiplayer link doesn't work (why include the link if it doesn't work?) and forces the player to close the game to get back to the main menu.
Lots and lots of problems, and I didn't even know how to play the game. All I did was fly around and shoot at the ships that were following me, even though I couldn't kill them.
