Swivel Turret Simon • nev-clock 16 February 2019 Animated gif showing my test game Swivel Turret. The game consists of a turret at the bottom of a screen that is constantly moving backwards and forwards as bombs fall from the top of the screen. Clicking the fire button fires the turret and when the bullets hit a bomb, the bomb explodes. Published 16th February 2019 at 376 × 681 in Developing a Reusable Instruction System
