Insecticide is another squash-the-bugs affair. You control a ladybird apparently armed with some sort of projectile weapon in a bid to clear a series of screens of other insect life.
A moth floats about and if you shoot it you can crawl faster for the rest of the level, it also shouts "Nairobi" when you hit it for some reason.
The sound effects are all sampled and rather smart. When things get too hot you can move your joystick diagonally and fly to a safer bit of the screen, although the joystick response is pretty ropey often dumping you on top of a nasty at the wrong moment.
The gameplay style is in the Llamatron mould; the enemy constantly moves towards you. It's nowhere near as smooth, hectic or addictive, though. Competent and marred by poor control response.
