Gorillas v2.0

Using Unity, the classic game Gorialls.bas has been remade. Updates include various powerups the player can select from, including a visible trajectory line, a scatter bomb, the ability to reposition their gorillas, and more. For best results play the game full screen.

From Wikipedia: 

Gorillas, also known under the source code's file name GORILLA.BAS, is a video game first distributed with MS-DOS 5 and published in 1990 by Microsoft.  It is a turn-based artillery game. With allusions to King Kong, the game consists of two gorillas throwing explosive bananas at each other above a city skyline. The players can adjust the angle and velocity of each throw.

Written in QBasic, it is one of the programs included as a demonstration of that programming language. The others are Nibbles (another game), Money (a simple financial calculator), and REMLINE (a program to remove line numbers from old BASIC programs).
