Hurrah! Or at least, “Hurrah to some extent!”.
I managed to get past stage 5, finally. That’s the sort of scrolly maze thing which requires pixel perfect ship maneuvering. As a result, I reached the Base Stage, but didn’t really know what I was supposed to do until I realised there was a thing I needed to shoot. I then remembered you could collide with the base, and you’d win (but not lose as life), so few at it, and missed.
My last life used up by hitting a wall. Bah. At least my score reached about 27,000-ish.
