I certainly think I could have done a lot more to match the color choices to the mood of the game.
A more desaturated background would have made the enemies and allies read easier better and fit the mood of the game better. As it is, the game feels a bit cheerful for the theme, but it still seems to read alright - perhaps because of the outlining, window mechanic, and green/brown domination in the relevant portions of the background.
I think with the time crunch I defaulted a bit toward EGA style without thinking about it here XD.
