The pig is facing the wrong direction, the background makes it impossible to see anything, and all the hitboxes are significantly larger than the object they go around.
I'm having trouble beating the boss, what am I supposed to do? I grabbed the fire and tried to burn him but that did not work, I also tried to climb the rope.
My suggestions: Scrolling background, better graphics for the ships, more enemy types. After playing this I can only think of one thing, we need Tyrian in flash.
A good 3D game in flash? There is one problem that a lot of early 3D racers on the PC/consoles had, when you touch the edge of the race track you come to almost a dead stop. May I suggest doing it like Burnout, where you slide against the side of the track allowing you to keep your forward movement while also allowing you to easily get away from the side of the track.
