Version 5.0 is now available for download with an all new simulation: 

Donkey Kong 3

A fast paced and challenging game where Stanley the Bugman and Donkey Kong are in a duel against each other using spray cans of insecticide to move bees across the screen and make them sting their opponents. But the bees move up and down the screen and there is only a limited supply of insecticide, which can be refilled, but the player's back is turned while refilling, rendering them defenseless.

Features a single player mode (Game A) where you play against the computer controlled Donkey Kong, or a two player mode (Game B) where you can play against a friend.
