               If your objects can be only 8 points wide, and 3 colors 
(you can use different colors from the backgroud), then go for sprites ... 
You'll be able to animate 8 objects very quickly (and that means in sync 
with the display, which is your goal for a game).

               Otherwise, you can quite easilly boost the blitter's perfs 
by programming it yourself. Remeber the graphics.lib routines where made 
for general purposes,  you can allways make a specific routine for your 
needs, and it'll be a lot faster. The only problem is that the blitter is 
not really easy to program by hand, and that you'll have to access it 
relatively to _custombase (don't do it otherwise than this way), it's a 
little dirty but if you need to modify it for a specific Amiga it can be 
do easilly.

             If you choose this solution, I strongly recomand you to get 
the program blitlab (Radical Eye software, it's PD), and it's 
documentation. Next buy some patience too (for the debuging) (-:
