Straight from Wiki : “Loom is a graphical adventure game originally released in 1990. It was both developed and published by Lucasfilm Games (now called LucasArts) and was the fourth game to use the SCUMM adventure game engine. The project was led by Brian Moriarty”.
Loom’s fantasy adventure unfolds as you, Bobbin, learn 4-note musical compositions that act as spells used throughout the game. The music is sourced from public domain classical works.
