The slightly underwhelming Big Boss' chamber, without the actual Big Boss (you get to fight him in the next level, tho!).
Was planning on adding some more stuff, but ran out of time- I expect a busy weekend :/
Also, if you think I did not follow the rules completely (it DOES say 'single-screen'), and that therefore this piece does not qualify for the weekly challenge, I will try and make a big mockup-type piece instead of this one.
I just feel this sort of presentation fits the style better (actual games' levels shown all at once often look... weird), and I made too much stuff to fit in a single small screen (GBC-sized, actually!).
