A small collection of Game-Maker games which I made in the mid 90's. Game-Maker was a DOS game engine which allowed novices such as myself to build simple games.
A game about earth worms and leeches, also known as annelids. Made in 1996 for a Year 7 school project.
Jim's Adventure Next Door, probably an unfinished game, from 1996.
A game about respiration, made in 1997 for a Year 8 school project. May contain heavily pixelated tile-based graphics which poorly depict the human anatomy.
