About 20 years ago, Microsoft released MS-DOS 5, and with it shipped a programming language called QBASIC. One of the samples that came with QBASIC is GORILLAS.BAS. The game used real-world Physics to make players hit each other with… wait for it… bananas. Come on, what did you expect from a game where the players are gorillas.
Fast forward to now. Rushworks has successfully captured the nostalgia with Gorillas for Small Basic. You can download and play the game by using the ID: NLQ667-2. The program listing is also available at: http://smallbasic.com/program/?NLQ667-2
