Two things
1.  So I finally got around to updating Axe 1.05, and started cleaning up my calculator, and found these games I made over the last six months.  Some of them you've probably already seen.
1a.Mirror Run-(MIRROR), source-AMIRROR, 2nd is start, Up and down move, Clear quits
1b.Runner(Canabalt clone)-(RUNNER), source-ARUNNERT, 2nd is start, up is jump, down is duck, Clear quits
1c.Falldown-(FALLDOWN), source-AFALLDOW, 2nd is start, Left and right move, Clear quits
1d.Bouncedown-(BOUNCEDN), source-ABOUNCE, 2nd is start, Del is delete highscore, Clear is quit, Left and Right move
1e.Slide-(SLIDE), source- ASLIDE, levels are GDB1-(1)0, 2nd to start, Del to kill yourself, Mode to show instructions, Arrow keys move, Clear quits, and yes I know the levels suck, I didn't really make any, I just kind of randomly placed tiles.

2.  I have decided to make a decent game this time, and to finish it.
The main idea is your this guy, in the future, and you shoot lots of stuff in a topdown perspective.

Here's the epic intro for the not so epic game:

Krillian Intro

   The year is 2²¹.  The age of technology and innovation is long gone.  Humans have regressed into barbarians, abandoning currency, government, art, and science, but keeping the superior weaponry of the past.  Earth is plagued with massive civil wars of all shapes and sizes.  Few retain the intelligence mankind was once known for.  Those few cannot innovate like they used to.  Instead, in order to survive, they must use their sheer intelligence and cunning to prevent further bloodshed.  You are one of the few.  You are Krillian.


So far I have most movement and a little bit of the machine gun done.
Arrow keys move, Clr quits, Numpad shoots.
I'm having some problems though.
A.When you press a lot of shoot buttons it shoots in the opposite direction too.
B.Downleft(1) shooting deosn't work.

I'm attaching a screenshot, the source.zip, and the actual game.

I'm not using Full. 

What do you mean about the keys?  For the bullets I'm storing them in an array, and I use this code to remove them:
If B
For (I,1,B)
{{I*5+L[sub]4[/sub]-1->J}-{J-2}->{J}}
{{I*5+L[sub]4[/sub]-2->K}-{K-2}->{K}}
If {J}>58
sub(RSB,I-1->I)
Elseif {K}>90
sub(RSB,I-1->I)
else
Pt-on({I*5+L[sub]4[/sub]-2->J},{J+1},Pic2)
End
End
End
B is the length of the array, which is (type, xspeed, yspeed, xposition, yposition).
Pic2 is the bullet.  J and K are the temporary Y and X of the current bullet.

Edit: Nevermind, I understand about the offset thing.  That part's fixed now.

I added yet another kind of machine gun bullet thing, and started to add enemies, however, as you can see in the screenshot, they are not working.
The screenshot shows the new kind of bullet( the tiny one) as well as the enemy bug.
I'm attaching the source and the game, Arrow keys move, clear exits, numpad shoots, + changes weapons, and 2nd adds enemies. 

What you can do is check the coordinates of the 8*8 sprites, and see if the numbers are close enough together.
