Arrows turn and move tank. Space bar shoots laser. Gun can turn independently of tank using A and D keys. Song serves as timer. A few seconds after the song is over the game ends and the winner is declared. Bugs score by escaping into green holes and the tank scores by shooting bugs. Tie goes to bugs! (The song is about an actual remote control robot that kills bugs using a laser.)
Project turned into a video called "Kill Bugs" which is available for viewing on the blackturtleshow channel at YouTube.
