Now and again a program really catches your fancy. This one went one better - it really got me excited. Excellent graphics - the variety of targets and the way they move, fantastic!
There are in fact, six screens of different targets, and each attacks differently; static, diagonal, zig-zag, vertical dive bombing.
Best of all is the tortoises. They move a bit then dodge into their shells and become impervious to your fire. To cap it all, on clearing the last screen, you have a nightdrive type, keep-the-ear-on-the-road course to complete.
But it's not just the variety packed into an unexpanded VIC that got me. There's the ammunition supply. To stop you just leaning on the fire button, the supply runs down as you fire and is slowly replenished when you pause.
Anyway, some of the targets will stop in their tracks rather than walk into a constant wall of vertical firing.
The kindest touch of all, other programmers please note, is that each screenful waits for you to start before it attacks you, thus allowing you to get your breath back/sip your coffee at frequent intervals. And you get four lives!
The top 2% of games experts may find this on the easy side. But for the rest of us it's an out and out winner.
