If you're still a Space Invaders fan, you'll enjoy this version. A mothership hovers over Earth releasing small attacking craft which you blow to bits with the aid of three cannons.

After enough craft have been zapped, the mothership takes off and the game resets quickly for the next wave.

Good graphics, and the movement is fast for TI Basic. If you beat a score of 5,000, you qualify for the hall of fame. I think that, at £10, the game is a bit overpriced, though.
