You could have PMed someone like the person who made Tag etc.
It would be easier

oh and as long as I'm here, progress update:
have designed 7 levels, with collisions for 6 of them.

ooh if I wanted to blow them up I would have to set up an alternate buffer and a whole bunch of other stuff...
anyone have an idea for an animation for when enemies are killed?

EDIT: an easy animation?

For mine, I started with a hole in the middle of the enemies and had the hole expand. It looked kinda like an explosion.

No I just had a few different sprites stored into the enemy pic

Ok. I made it a little more confusing then it needed to be since I used one variable for both the health and the explosion. I'll go get some codez.

Here's what I did:

.In the beginning
[normal enemy sprite]->Pic3
[an explosion sprite]
[an explosion sprite]
[an explosion sprite]
[an explosion sprite]
.Lotsa stuffs
.After the enemies have been killed and the kill code is done
For(P,0,r5)
.P*3+L2 is the explosion frame count/Enemy life
If {P*3+L2}<6
. ^ If the frame count is less than 6 (I dont think I need the first if )
!If {P*3+L2+2}
.P*3+L2+2 is alive or dead ^ (I need this because P*3+L2 is also the health amount)
.If I didnt do that, it would start the animation when the enemy is still alive
Pt-On({P*2+L1},{P*2+L1+1},{P*3+L2}*8+Pic3-1)
.Display the pics ^.
{P*3+L2}++
.Add to frame count^
If {P*3+L2}=5
. If the frame is at 5 (which is the end of the final frame)
K++
. Add one to the amt of enemies killed.
End
End
End
End

Oh, r5 was the number of enemies. Mine was at 4.

Replace the vars with what you are using

Replace P*3+L2 with what var you store the enemies life to.

Replace P*3+L2+2 with what var you use to tell if the enemy is alive or dead (If you dont have that... Youll have to change up the animation code a bit)

Replace P*2+L1 with what var you store the enemies X coordinate to.


Also, you forgot to put in the for. It needs to check all the enemies

For(P,0,num of enemies on screen)

I dont know how you coded your game, so you might have to change a bit

Notice: I was too lazy to put the curly brackets in this post

Update: Here's the first 6 levels, hope you can beat them!  
please post any bugs
EDIT: screenie!
