Noise Raiser was made for the MSX 1st Experimental Sound Mini-Compo at Karoshi's Forum.
The inital idea was to make something related to generative music, but then it went towards a more wide area, like experimental music.
The goal was to provide some kind of interact with the user. This way, the user can also modify some things, like character's direction, wall positions, action positions and parameters of the ones. So the user has control over the resulting... noise. It's not just random stuff. But it can easily be.
The result could be a total mess or something more or less rythmical... a loop.
