about the the black cubes things, i originally wanted it to be some kind of materials which you salvage from the enemies, and the low would be to repurpose the material to materialize things.
Turns out i never get to implement these and still calling it material is also confusing.
But yea, maybe i shouldn't cling to the "material" thing to much and just make it orange or something. Making it too dark just makes it look like poisonous or something.
