Converted from the Commodore - perhaps something got lost in the translation. You shoot at aliens and their bombs revolving in a large circle, while bombs detonate and unhit objects reflect your fire. Okay in theory, but all eight sections are identical, and the aliens are just too damn fast! I bust a gut to reach level 5 with 65000, only to start again and get 54000 without touching a key. No answers on a postcard please - I lost interest hours ago.
