Thanks, I like the minimalist art style, but I think for practicality sake, there should be detail.
For example, you can't really tell what weapon the guys are holding.
The art style is inspired by Rebel Star Raiders, a game built on the zxSpectrum (Z80 CPU
And laser squad.
MOS used to stand for something, but I don't recall it.
I'm thinking of Mail Operations and Services. (The guys wear pseudo-mailmen uniforms :^) )
