i'm already noticing a TON of issues. First off, making the player switch the gun back and forth is ok, but relatively pointless when you've already added the spacebar for rockets. Why not EITHER have to press space OR control the gun? this sort of 2d racing game really falls apart when it gets too complicated...
the turret attacked crates which were necessary to make certain jumps, and frequently was more of a boon than it was helpful, and within the first 20 seconds i noticed that rockets move at a sluggish and unrealistic pace, and literally never hit the target until i had either passed it or been slowed down to a near stop by ramming it so much.
i liked the original, and im happy that you've gone on to make more, but this is honestly just garbage.
the only real improvement that i see is a prettier interface with fancier menus. If you were to fix the rockets, make the gun either auto target or aim with the mouse, and fix the fact that the gun auto attacks crates which are necessary to complete jumps and reach certain areas, i would play this. otherwise, this is just a waste of my time.
especially after reading other reviews which state that the game stops working at the third tier and has lag issues, i just cant say that it is worthwhile for me to play past the first level. You've already kind of ruined a classic for me, and i mean that in the least antagonistic, most helpful way that i can...
