Encouraged by the name (a Tomcat, apart from being a feline of the male gender, is a rather spanky US Navy plane), and, in sheer desperation, I decided to give this one a whirl. Bad idea. It's a very ordinary vertically-scrolling shooter with one outstanding feature - it's completely impossible to get anywhere in. The aeroplane theme is a bit weak too, as you could easily replace it with a spaceship or something and not notice the difference. Still no joy then.
Um, will somebody please tell me if I've taken off yet?
