Bug is an alien insect from another galaxy. He fell on planet Earth and found himself in a forest full of dangers. In the game, the player has to help Bug through the forest avoiding obstacles and enemies he encounters along the way. The player must use quick reflexes and ingenuity to successfully traverse the forest. The enemies are varied; saws trying to cut Bug, cannonballs crashing into him, vampire bugs trying to suck his blood and much more. But there are also nice things: bonuses to help Bug progress, cute music and cool animations.
