Yup, exactly!

The current kernel is quite simple and makes no difference between cave
and not cave areas. Currently there are 69 cycles free, but I'll need
about ~20 cycles if I want the top and bottom caves overlap (switching
kernels!) and make the colors move when scrolling up and down.
So two objects should be easily possible. And *maybe* a simple missile
or ball.

Currently I can scroll up to 1 PF-pixel/frame. More seems to be no
problem for the kernel, but the setup code needs some optimization then.
It's already quite long and I was planning to spread it over different
frames (e.g. odd/even, if possible).
Bi-directional scrolling should be not problem, I only need a
bi-directional random-number generator (like in Pitfall!). And some extra
code of course. :-)

Yes, that's probably a good game idea for paddles, isn't it?

Hm, I think I don't have enough time for that.

Hm ,I *know* I don't have enough time for that. :-)

Sorry, but I don't understand how that idea fits to my current kernel.
Can you explain that a bit more detailed, please?

But we have that already, haven't we? ;-)

Yup, that is the more complex approach for the gameplay I had in my
mind.
Have fun!
