That's a really nice look you have going on there mate

Nice to see something new by you always and I totally love those asteroids!
There are so many cool things you cann add to this, as benny said, the style of highlighting the points is effective, I guess that I'd love it even more if there was a bit of glow on the image, to remind me of the display on the vectrex.
Even without the glow it looks very effective.
