something fishy
This is one of those games that is easier if you shoot less, which you are rewarded for anyway (it has points ratios for hit-miss stats.)

For unknown reasons, the (factory sealed) copy I had (from elsewhere, hope I can still review it here) has no options at all, despite them featuring in the manual. This sadly includes no continues, which are handy when you just want to see all the levels. And there's a lot of levels, about 26.

Lovely colours, great speed and controls, brilliant music.
