I am NOT the requesting guy,but
think some maps need to be rewritten.
If a slum under a plate looks green like in this game I would like to live in a place like that.The power plants and town outsides should look more like cyberpunk.
This game features airships instead of helis but the player cant use one,
while in every FF game there is alt least 1 airship available to use.
thought about recommending you games to rip tiles and sprites but that would be
the same way this game was created
other NES games have a much more interesting dungeon style
About the creepy music
: is from FF3,but the battle music is from FF2
