Insector-X

Mecha Insect forces collide in this side-scrolling shooter, set in a garden,
passing buildings and other scenery. Fight wasps, bees and flies to decide the
fate of the back yard.

There are three skill levels, with more enemies on the higher ones, and each
level ends with a boss. As well as your main weapon, who can collect power-up
tokens for special weapons, which are made available randomly.
