I had made a couple of small games ages ago, most of which never went anywhere, and only recently started playing around with Pico-8, which I LOVE. Got together with my mate andy who has a similar background. We were surprised how far we got in one and a half days, and had a blast. We did everything in Pico-8 -- in case you don't know it, check it out if you like pixel graphics and like working under constraints that can occasionally breed creativity.
In terms of the idea... we quickly thought of the sort of gameplay we'd enjoy and could realistically pull of in the given time-frame, and just made our protagonists (or antagonists) miniature - 2 single pixels.
How about you, Kebab? I loved your game btw., a proper piece of art!
