Pesterminator

The nine levels are pretty straightforward side-scrolling platform stages, with a nice twist in level 5, 7 and 8.1 (a helicopter, underwater and moon surface level respectively). While playing, you can view a status report with the remaining bugs to be found. Some defeated enemies leave behind hearts (extra lives) and the final level introduces an adventure element when you have to find a key card to open the door to Ronnie's lair.
