TECHNICAL FEATURES SHOWN IN THE VIDEO

• 3 parallax layers scrolling at a variable speed (up to 16 pixels/frame - such limit is not technical, but only to keep the game playable)
• 1 fixed layer for the HUD (and possibly other graphical effects)
• Real transparencies (each color can have any 8 bit degree of transparency)
• A 16 colors sprite plus a 3 colors sprite

NOTES

• The music is a temporary placeholder; it's the fabulous tracker module Cortouchka by El Mobo/Frédéric Motte
• Despite the video was uploaded in lossless quality, the compression applied by YouTube degraded it a lot.
