Ahhh, I remember playing Jetpac on the ZX Spectrum....Good times. This is a decent recreation, although I would have preferred a retro style remake instead of a graphically enhanced one. Oh well.
No offenses or anything man, but this is a dead copy of the code. All you did was make a couple levels for it. I mean, you even used the artwork included with the tutorial! C'mon, your better then this!
I personally hated this game. Not because of the sounds, or the levels being copies of Red Remover's, but the fact you made a whole game using the Circle shape in Box2D. With how unreliable that game engine already is, you took the most unreliable part of it, and made 20 levels with pars based on luck.
And regarding the preloader loading last in the Flash, I don't know why it does it. Nothing is exported on the first frame, the flash just loads the first frame last. Never happened to me before.
And thanks to the nice users that realized that and have corrected the other users that apparently can't waste 5 seconds on research. I guess this is the first and last time I do a tutorial on something in Flash.
And shooting games are copying Mario only shooting instead of jumping. In shift, you move into the level and it flips. In Invert, the level flips on the Y axis (instead of x like in shift) and you don't go in the level, you get a different area of the level.
