Construction

Construction -Video Game Kit- (コンストラクション -ビデオゲーム・キット-) is a video game editor created by Toshio Fujita. The command options are displayed in English despite its country of origin. A sequel was later released six months afterwards.

Gameplay
While the game itself is seemingly a Pac-Man clone at first glance, it enables players to edit maze layouts, sound effects, and character graphics through the use of command inputs. Tweaking the game's speed and positioning enemies are also available options. Players can then save their creations and load them for others to try.
