Scout: not yet. I'd like to perfect the engine before I put anything new in it.

Yeah that's the way to go

That way I run less risk of breaking enemies when I make things better.

NEW XY!!!!!!!
I'm implementing my own, much altered, barely recognizable version of Bresenham's algorithm. It's not that I don't appreciate all the help everyone has provided, I just didn't get to a computer in time
I'm very proud of the fact that I have all eight directions Covered in one loop.
Here's my line algorithm:
X=X2
Y=Y2
T=X1
U=Y1

X-T->A
Y-U->B
A>>0-(A<<0)->I
B>>0-(B<<0)->J
abs(A)->C
abs(B)->D
If C>=D
C->H
Else
D->H
End
For(Q,0,H
Pxl-On(Q*A//H+T,Q*B//H+U
End
DispGraphClrDraw

Get it over here!

EDIT: I posted the wrong algorithm. Whoops. X.X

Okay, there's an engine. Where's gameplay at?

Velocity is high=You seem to move in a straight line beacuse gravity is low?

Things move in straight lines in xy because time is quantized, so gravity only affects things once a time quantum passes. A "tick", if you will. Things travel in straight lines until something acts upon them, ie another tick occurs and gravity affects them again. This is not appearent at low speeds because ticks happen before it gets too far, creating the illusion of a curve.
DJ, when you press an arrow key, it doesn't affect the perpendicular direction of gravity. Hold down Alpha to show gravity direction

You're very welcome.

Here's a screenie for y'all
Note: runs faster on real calc.

The difference is in direction only. The reason that set of arrows is bold is because I couldn't find a character that matched the other three arrows, so I decided to go with that one.
At one point (this was never uploaded) you could change the ball diameter on the fly from 8 all the way down to one. I realized that the only way I could get a feasible collision engine going was if the ball diameter was 1, so, yeah.
